Tableau Sales Dashboard Performance

The following is a guest post contributed by Perceptive Analytics.

Business heads often use KPI tracking dashboards that provide a quick overview of their company’s performance and well-being. A KPI tracking dashboard collects, groups, organizes and visualizes the company’s important metrics either in a horizontal or vertical manner. The dashboard provides a quick overview of business performance and expected growth.

An effective and visually engaging way of presenting the main figures in a dashboard is to build a KPI belt by combining text, visual cues and icons. By using KPI dashboards, organizations can access their success indicators in real time and make better informed decisions that support long-term goals.

What is a KPI?

KPIs (i.e. Key Performance Indicators) are also known as performance metrics, performance ratios or business indicators. A Key Performance Indicator is a measurable value that demonstrates how effectively a company is achieving key business objectives.

A sales tracking dashboard provides a complete visual overview of the company’s sales performance by year, quarter or month. Additional information such as the number of new leads and the value of deals can also be incorporated.

Example of KPIs on a Sales Dashboard:

  • Number of New Customers and Leads
  • Churn Rate (i.e. how many people stop using the product or service)
  • Revenue Growth Rate
  • Comparison to Previous Periods
  • Most Recent Transactions
  • QTD (quarter to date) Sales
  • Profit Rate
  • State Wise Performance
  • Average Revenue for Each Customer

Bringing It All Together with Dashboards and Stories

An essential element of Tableau’s value is delivered via dashboards. Well-designed dashboards are visually engaging and draw in the user to play with the information. Dashboards can facilitate details-on-demand that enable the information consumer to understand what, who, when, where, how and perhaps even why something has changed.

Best Practices to Create a Simple and Effective Dashboard to Observe Sales Performance KPIs

A well-framed KPI dashboard instantly highlights problem areas. The greatest value of a modern business dashboard lies in its ability to provide real-time information about a company’s sales performance. As a result, business leaders, as well as project teams, are able to make informed and goal-oriented decisions, acting on actual data instead of gut feelings. The choice of chart types on a dashboard should highlight KPIs effectively.

Bad Practices Examples in a Sales Dashboard:

  • A sales report displaying 12 months of history for twenty products; 12 × 20 = 240 data points.
    • Multiple data points do not enable the information consumer to effectively discern trends and outliers as easily as a time-series chart comprised of the same information
  • The quality of the data won’t matter if the dashboard takes five minutes to load
  • The dashboard fails to convey important information quickly
  • The pie chart has too many slices, and performing precise comparisons of each product sub-category is difficult
  • The cross-tab at the bottom requires that the user scroll to see all the data

Now, we will focus on the best practices to create an effective dashboard to convey the most important sales information. Tableau is designed to supply the appropriate graphics and chart types by default via the “Show me” option.

I. Choose the Right Chart Types

With respect to sales performance, we can use the following charts to show the avg. sales, profits, losses and other measures.

  • Bar charts to compare numerical data across categories to show sales quantity, sales expense, sales revenue, top products and sales channel etc. This chart represents sales by region.

1

  • Line charts to illustrate sales or revenue trends in data over a period of time:

2

  • A Highlight table allows us to apply conditional formatting (a color scheme in either a continuous or stepped array of colors from highest to lowest) to a view.

3

  • Use Scatter plots or scatter graphs to investigate the relationship between different variables or to observe outliers in data. Example: sales vs profit:

4

  • Use Histograms to see the data distribution across groups or to display the shape of the sales distribution:

5

Advanced Chart Types:

  • Use Bullet graphs to track progress against a goal, a historical sales performance or other pre-assigned thresholds:

6

  • The Dual-line chart (or dual-axis chart), is an extension of the line chart and allows for more than one measure to be represented with two different axis ranges. Example: revenue vs. expense
  • The Pareto chart is the most important chart in a sales analysis. The Pareto principle is also known as 80-20 rule; i.e roughly 80% of the effects come from 20% of the causes.

7

When performing a sales analysis, this rule is used for detecting the 80% of total sales derived from 20% of the products.

  • Use Box plots to display the distribution of data through their quartiles and to observe the major data outliers

8

Tableau Sales Dashboard

Here is a Tableau dashboard comprised of the aforementioned charts. This interactive dashboard enables the consumer to understand sales information by trend, region, profit and top products.

II. Use Actions to filter instead of Quick Filters

Using actions in place of Quick Filters provides a number of benefits. First, the dashboard will load more quickly. Using too many Quick Filters or trying to filter a very large dimension set can slow the load time because Tableau must scan the data to build the filters. The more quick filters enabled on the dashboard, the longer it will take the dashboard to load.

III. Build Cascading Dashboard Designs to Improve Load Speed

By creating a series of four-panel, four cascading dashboards the load speed was improved dramatically and the understandability of the information presented was greatly enhanced. The top-level dashboard provided a summary view, but included filter actions in each of the visualizations that allowed the executive to see data for different regions, products, and sales teams.

IV. Remove All Non-Data-Ink

Remove any text, lines, or shading that doesn’t provide actionable information. Remove redundant facts. Eliminate anything that doesn’t help the audience understand the story contained in the data.

V. Create More Descriptive Titles for Each Data Pane

Adding more descriptive data object titles will make it easier for the audience to interpret the dashboard. For example:

  • Bullet Graph—Sales vs. Budget by Product
  • Sparkline—Sales Trend
  • Cross-tab—Summary by Product Type
  • Scatter Plot—Sales vs. Marketing Expense

VI. Ensure That Each Worksheet Object Fits Its Entire View

When possible, change the graphs fit from “Normal” to “Entire View” so that all data can be displayed at once.

VII. Adding Dynamic Title Content

There is an option to use dynamic content and titles within Tableau. Titles can be customized in a dynamic way so that when a filter option is selected, the title and content will change to reflect the selected value. A dynamic title expresses the current content. For example: if the dashboard title is “Sales 2013” and the user has selected year 2014 from the filter, the title will update to “Sales 2014”.

VIII. Trend Lines and Reference Lines

Visualizing granular data sometimes results in random-looking plots. Trend lines help users interpret data by fitting a straight or curved line that best represents the pattern contained within detailed data plots. Reference lines help to compare the actual plot against targets or to create statistical analyses of the deviation contained in the plot; or the range of values based on fixed or calculated numbers.

IX. Using Maps to Improve Insight

Seeing the data displayed on a map can provide new insights. If an internet connection is not available, Tableau allows a change to locally-rendered offline maps. If the data includes geographic information, we can very easily create a map visualization.

10

This map represents sales by state. The red color represents negative numbers and the green color represents positive numbers.

X. Developing an Ad Hoc Analysis Environment

Tableau facilitates ad hoc analysis in three ways:

  1. Generating new data with forecasts
  2. Designing flexible views using parameters
  3. Changing or creating designs in Tableau Server

XI. Using Filters Wisely

Filters generally improve performance in Tableau. For example, when using a dimension filter to view only the West region, a query is passed to the underlying data source, resulting in information returned for only that region. We can see the sales performance of the particular region in the dashboard. By reducing the amount of data returned, performance improves.

Enhance Visualizations Using Colors, Labels etc.

I. Using colors:

Color is a vital way of understanding and categorizing what we see. We can use color to tell a story about the data, to categorize, to order and to display quantity. Color helps with distinguishing the dimensions. Bright colors pop at us, and light colors recede into the background. We can use color to focus attention on the most relevant parts of the data visualization. We choose color to highlight some elements over others, and use it to convey a message.

Red is used to denote smaller values, and blue or green is used to denote higher values. Red is often seen as a warning color to show the loss or any negative number whereas blue or green is seen as a positive result to show profit and other positive values.

Without colors:

11

With colors:

12

II. Using Labels:

Enable labels to call out marks of interest and to make the view more understandable. Data labels enable comprehension of exact data point values. In Tableau, we can turn on mark labels for marks, selected marks, highlighted marks, minimum and maximum values, or only the line ends.

Without labels:

13

With labels:

14Using Tableau to enhance KPI values

The user-friendly interface allows non-technical users to quickly and easily create customized dashboards. Tableau can connect to nearly any data repository, from MS Excel to Hadoop clusters. As mentioned above, using colors and labels, we can enhance visualization and enhance KPI values. Here are some additional ways by which we can enhance the values especially with Tableau features.

I. Allow for Interactivity

Playing, exploring, and experimenting with the charts is what keeps users engaged. Interactive dashboards enable the audiences to perform basic analytical tasks such as filtering views, drilling down and examining underlying data – all with little training.

II. Custom Shapes to Show KPIs

Tableau shapes and controls can be found in the marks card to the right of the visualization window. There are plenty of options built into Tableau that can be found in the shape palette.

15

Custom shapes are very powerful when telling a story with visualizations in dashboards and reports. We can create unlimited shape combinations to show mark points and create custom formatting. Below is an example that illustrates how we can represent the sales or profit values with a symbolic presentation.

16

Here green arrows indicate good sales progress and red arrows indicate a fall in Year over Year Sales by Category

III. Creating Calculated Fields

Calculated fields can be used to create new dimensions such as segments, or new measures such as ratios. There are many reasons to create calculated fields in Tableau. Here are just a few:

  1. Segmentation of data in new ways on the fly
  2. Adding a new dimension or a new measure before making it a permanent field in the underlying data
  3. Filtering out unwanted results for better analyses
  4. Using the power of parameters, putting the choice in the hands of end users
  5. Calculating ratios across many different variables in Tableau, saving valuable database processing and storage resources

IV. Data-Driven Alerts

With version 10.3, Tableau has introduced a very useful feature: Data-Driven Alerts. We may want to use alerts to notify users or to remind that a certain filter is on and want to be alerted somehow if performance is ever higher or lower than expected. Adding alerts to dashboards can help elicit necessary action by the information consumer. This is an example of a data driven alert that we can set while displaying a dashboard or worksheet.

17

In a Tableau Server dashboard, we can set up automatic mail notifications to a set of recipients when a certain value reaches a specific threshold.

Summary

For an enterprise, a dashboard is a visual tool to help track, monitor and analyze information about the organization. The aim is to enable better decision making.

A key feature of sales dashboards in Tableau is interactivity. Dashboards are not simply a set of reports on a page; they should tell a story about the business. In order to facilitate the decision-making process, interactivity is an important part of assisting the decision-maker to get to the heart of the analysis as quickly as possible.

Tableau for Marketing: Become a Segmentation Sniper

This article is a guest post contributed by Perceptive Analytics.

Did you know that Netflix has over 76,000 genres to categorize its movie and tv show database? I am sure this must be as shocking to you as this was to me when I read about it first. Genres, rather micro-genres, could be as granular as “Asian_English_Mother-Son-Love_1980.” This is the level of granularity to which Netflix has segmented its product offerings, which is movies and shows.

But do you think is it necessary to go to this level to segment the offerings?

I think the success of Netflix answers this question on its own. Netflix is considered to have one of the best recommendation engines. They even hosted a competition on Kaggle and offered a prize money of USD 1 million to the team beating their recommendation algorithm. This shows the sophistication and advanced capabilities developed by the company on its platform. This recommendation tool is nothing but a segmentation exercise to map the movies and users. Sounds easy, right?

Gone are the days when marketers used to identify their target customers based on their intuition and gut feelings. With the advent of big data tools and technologies, marketers are relying more and more on analytics software to identify the right customer with minimal spend. This is where segmentation comes into play and makes our lives easier. So, let’s first understand what is segmentation? and why do we need segmentation?

Segmentation, in very simple terms, is grouping of customers in such a way that that customers falling into one segment have similar traits and attributes. The attributes could be in terms of their likings, preference, demographic features or socio-economic behavior. Segmentation is mainly talked with respect to customers, but it can refer to products as well. We will explore few examples as we move ahead in the article.

With tighter marketing budgets, increasing consumer awareness, rising competition, easy availability of alternatives and substitutes, it is imperative to use marketing budgets to prudently to target the right customers, through the right channel, at the right time and offer them the right set of products. Let’s look at an example and understand why segmentation is important for marketers.

There is an e-commerce company which is launching a new service for a specific segment of customers who shop frequently and whose ticket size is also high. For this, the company wants to see which all customers to target for the service. Let’s first look at the data at an aggregate level and then further drill down to understand in detail. There are 5 customers for whom we want to evaluate the spend. The overall scenario is as follows:

Chart1

Should the e-commerce company offer the service to all the five customers?

Who is the right customer to target for this service? Or which is the right customer segment to target?

We will see the details of each of the customers and see the distribution of data.

2

Looking at the data above, it looks like Customer 1 and Customer 2 would be the right target customers for company’s offering. If we were to segment these 5 customers into two segments, then Customer 1 and Customer 2 would fall in one segment because they have higher total spend and higher number of purchases than the other three customers. We can use Tableau to create clusters and verify our hypothesis. Using Tableau to create customer segments, the output would look like as below.

3

Customer 1 and customer 2 are part of cluster 1; while customer 3, customer 4 and customer 5 are part of cluster 2. So, the ecommerce company should focus on all the customers falling into cluster 1 for its service offering.

Let’s take another example and understand the concept further.

We will try to segment the countries in the world by their inbound tourism industry (using the sample dataset available in Tableau). Creating four segments we get the following output:

4

There are few countries which do not fall into any of the clusters because data for those countries is not available. Looking at clusters closely, we see that the United States of America falls in the cluster 4; while India, Russia, Canada, Australia, among others fall in the cluster 2. Countries in the Africa and South America fall in the cluster 1; while the remaining countries fall in the cluster 3. Thus, it makes it easier for us to segment countries based on certain macro-economic (or other) parameters and develop a similar strategy for countries in the same cluster.

Now, let’s go a step further and understand how Tableau can help us in segmentation.

Segmentation and Clustering in Tableau

Tableau is one of the most advanced visualization and business intelligence tool available in the market today. It provides a lot of interactive and user-friendly visualizations and can handle large amounts of data. It can handle millions of rows at once and provides connection support to almost all the major databases in the market.

With the launch of Tableau 10 in 2016, the company offered a new feature of clustering. Clustering was once considered a technique to be used only by statisticians and advanced data scientists, but with this new feature in Tableau it becomes as easy as simple drag and drop. This feature can provide a big support to marketers in segmenting their customers and products, and get better insights.

Steps to Becoming a Segmentation Sniper

Large number of sales channels, increase in product options and rise in advertisement cost has made it inevitable not only for marketers but for almost all the departments to analyze customer data and understand their behavior to maintain market position. We will now take a small example and analyze the data using Tableau to understand our customer base and zero-in on the target customer segment.

There is a market research done by a publishing company which is mainly into selling of business books. They want to further expand their product offerings to philosophy books, marketing, fiction and biographies. Their objective is to use customer responses and find out which age group like which category of books the most.

For an effective segmentation exercise, one should follow the below four steps.

  1. Understand the objective
  2. Identify the right data sources
  3. Creating segments and micro-segments
  4. Reiterate and refine

We will now understand each of the steps and use Tableau, along with, to see the findings at every step.

  1. Understand the objective

Understanding the objective is the most important thing that you should do before starting the segmentation exercise. Having a clear objective is the most imperative thing because it will help you channelize your efforts towards the objective and prevent you from just spending endless hours in plain slicing and dicing. In our publishing company example, the objective is to find out the target age group which the company should focus on in each of the segments, namely philosophy, marketing, fiction and biography. This will help the publishing company in targeting its marketing campaign to specific set of customers for each of the genres. Also, it will help the company in identifying the target age group that like both business and philosophy or business and marketing, or similar other groups.

  1. Identify the right data sources

In this digital age, data is spread across multiple platforms. Not using the right data sources could prove to be as disastrous as not using analytics at all. Customer data residing in CRM systems, operational data in SAP systems, demographic data, macro-economic data, financial data, social media footprint – there could be endless list of data sources which could prove to be useful in achieving our objective. Identifying right variables from each of the sources and then integrating them to form a data lake forms the basis of further analysis.

In our example, dataset is not as complex as it might be in real life scenarios. We are using a market survey data gathered by a publishing company. The data captures the age of customer and their liking/disliking for different genres of books, namely philosophy, marketing, fiction, business and biography.

  1. Creating segments and micro-segments

At this stage, we have our base data ready in the analyzable format. We will start analyzing data and try to form segments. Generally, you should start by exploring relationships in the data that you are already aware of. Once you establish few relationships among different variables, keep on adding different layers to make it more granular and specific.

We will start by doing some exploratory analysis and then move on to add further layers. Let’s first see the results of the market survey at an aggregate level.

5

From the above analysis, it looks like fiction is the most preferred genre of books among the respondents. But before making any conclusions, let’s explore a little further and move closer to our objective.

If we split the results by age group and then analyze, results will look something like the below graph.

6

In the above graph, we get further clarity on the genre preferences by respondents. It gives us a good idea as to which age group prefers which genre. Fiction is most preferred by people under the age of 20; while for other age groups fiction is not among the top preference. If we had only taken the average score and went ahead with that, we would have got skewed results. Philosophy is preferred by people above the age of 40; while others prefer business books.

Now moving a step ahead, for each of the genre we want to find out the target age group.

7

The above graph gives us the target group for each of the genres. For biography and philosophy genres, people above the age of 40 are the right customers; while for business and marketing, age group 20-30 years should be the target segment. For fiction, customers under the age of 20 are the right target group.

Reiterate and refine

 In the previous section, we created different customer segments and identified the target segment for publishing company. Now, let’s say we need to move one more step ahead and identify only those age groups and genres which have overlap with business genres. To put it the other way, if the publishing company was to target only one new genre (remember, they already have customer base for business books) and one age group, which one should it be?

Using Tableau to develop a relation amongst the different variables, our chart should look like the one below.

8

Starting with the biography genre, age group 30-40 years comes closest to our objective, i.e., people in this age group like both biography and business genre (Biography score – 0.22, Business score – 0.31). Since, we have to find only one genre we will further explore the relationships.

For fiction, there is no clear overall with any of the age groups. For marketing, age group 20-30 year looks to be clear winner. The scores for the groups are – marketing – 0.32, business – 0.34. The relation between philosophy and business is not as strong as it is for business and marketing.

To sum it up, if the publishing company was to launch one more genre of books then it should be marketing and target customer group should be in the range of 20-30 years.

Such analysis can be refined further depending on the data we have. We can add gender, location, educational degree, etc. to the analysis and further refine our target segment to make our marketing efforts more focused.

I think after going through the examples in the article, you can truly appreciate the level of segmentation that Netflix has done and it clearly reflects the reason behind its success.

Tableau Filtering Actions Made Easy

This is a guest post provided by Vishal Bagla, Chaitanya Sagar, and Saneesh Veetil of Perceptive Analytics.

Tableau is one of the most advanced visualization tools available on the market today. It is consistently ranked as a ‘Leader’ in Gartner’s Magic Quadrant. Tableau can process millions of rows of data and perform a multitude of complex calculations with ease. But sometimes analyzing large amounts of data can become tedious if not performed properly. Tableau provides many features that make our lives easier with respect to handling datasets big and small, which ultimately enables powerful visualizations.

Tableau’s filtering actions are useful because they create subsets of a larger dataset to enable data analysis at a more granular level. Filtering also aids user comprehension of data. Within Tableau data can be filtered at the data source level, sheet level or dashboard level. The application’s filtering capabilities enable data cleansing and can also increase processing efficiency. Furthermore, filtering aids with unnecessary data point removal and enables the creation of user defined date or value ranges. The best part is that all of these filtering capabilities can be accessed by dragging and dropping. Absolutely no coding or elaborate data science capabilities are required to use these features in Tableau.

In this article, we will touch upon the common filters available in Tableau and how they can be used to create different types of charts. After reading this article, you should be able to understand the following four filtering techniques in Tableau:

  1. Keep Only/Exclude Filters
  2. Dimension and Measure Filters
  3. Quick Filters
  4. Higher Level Filters

We will use the sample ‘Superstore’ dataset built in Tableau to understand these various functions.

1. Keep Only/Exclude Filters in Tableau

These filters are the easiest to use in Tableau. You can filter individual/multiple data points in a chart by simply selecting them and choosing the “Keep Only” or “Exclude” option. This type of filter is useful when you want to focus on a specific set of values or a specific region in a chart.

While using the default Superstore dataset within Tableau, if we want to analyze sales by geography, we’d arrive at the following chart.

1.png

However, if we want to keep or exclude data associated with Washington state, we can just select the “Washington” data point on the map. Tableau will then offer the user the option to “Keep Only” or “Exclude”. We can then simply choose the option that fits our need.

2.png

2. Dimension and Measure Filters

Dimension and measure filters are the most common filters used while working with Tableau. These filters enable analysis at the most granular level. Let’s examine the difference between a dimension filter and a measure filter.

Dimension filters are applied to data points which are categorical in nature (e.g. country names, customer names, patient names, products offered by a company, etc.). When using a dimension filter, we can individually select each of the values that we wish to include or exclude. Alternatively, we can identify a pattern for the values that we wish to filter.

Measure filters can be applied to data points which are quantitative in nature, (e.g. sales, units, etc.). For measure filters, we generally work with numerical functions such as sum, average, standard deviation, variance, minimum or maximum.

Let’s examine dimension filters using the default Tableau Superstore dataset. The chart below displays a list of customers and their respective sales.

3.png

Let’s examine how to exclude all customers whose names start with the letter ‘T’ and then subsequently keep only the top 5 customers by Sales from the remaining list.

One way would be to simply select all the customers whose names start with ‘T’ and then use the ‘Exclude’ option to filter out those customers. However, this is not a feasible approach when we have hundreds or thousands of customers. We will use a dimension filter to perform this task.

When you move the Customer Name field from the data pane to the filters pane, a dialogue box like the one shown below will appear.

4.png

As shown in the above dialogue box, you can select all the names starting with “T” and exclude them individually. The dialogue box should look like the one shown below.

5.png

The more efficient alternative is to go to the Wildcard tab in the dialogue box and select the “Exclude” check box. You can then choose the relevant option “Does not start with”.

6.png

To filter the top 5 customers by sales, right click on “Customer Name” in the Filters area, select “Edit Filter” and then go to the “Top” tab in the filter dialogue box. Next, choose the “By Field” option. Make your selections align to the following screenshot.

top-5-customers-by-sales-filter

After performing the necessary steps, the output will yield the top 5 customers by sales.

top 5 customers by sales

Let’s move on to measure filtering within the same Tableau Superstore dataset. We’re going to filter the months where 2016 sales were above $50,000. Without a measure filter applied, our sales data for 2016 would look like the following:

9.png

To filter out the months where sales were more than $50,000, move the sales measure from the data pane to the filter pane. Observe the following:

10.png

Here, we can choose any one of the filter options depending upon our requirement. Let’s choose sum and click on “Next”. As shown below, we are provided with four different options.

11.png

We can then choose one of the following filter options:

  • Enter a range of values;
  • Enter the minimum value that you want to display using the “At least” tab;
  • Enter the maximum value that you want to display using the “At most” tab;
  • From the Special tab, select “all values”, “null values” or “non-null” values;

Per our example, we want to filter for sales that total more than $50,000. Thus, we will choose the “At least” tab and enter a minimum value of 50,000.

12.png

In the output, we are left with the six months (i.e. March, May, September, October, November, December) that have a sum of sales that is greater than $50,000.

13.png

Similarly, we can choose other options such as minimum, maximum, standard deviation, variance, etc. for measure filters. Dimension and measure filters make it very easy to analyze our data. However, if the dataset is very large, measure filters can lead to slow performance since Tableau needs to analyze the entire dataset before it filters out the relevant values.

3. Quick Filters

Quick filters are radio buttons or check boxes that enable the selection of different categories or values that reside in a data field. These filters are very intuitive and infuse your visualizations with additional interactivity. Let’s review how to apply quick filters in our Tableau sheet.

In our scenario, we have sales data for different product segments and different regions from 2014 to 2019. Our data looks like the following:

14.png

We want to filter the data by segments and see data for only two segments (Consumer and Corporate). One way to do this would be to use a dimension filter, but what if we want to compare segments and change the segment every now and then? In this scenario, a quick filter would be a useful addition to the visualization. To add a quick filter, right click on the “Segment” dimension in Marks pane and choose “Show Filter”.

15.png

Once we click on “Show Filter”, a box will appear on the right side of the Tableau screen. The box contains all constituent values of the Segment dimension. At this point, we could choose to filter on any segment value available in the quick filter box. If we were to select both Consumer and Corporate values, Tableau will display two charts instead of three.

16

Similarly, we can add other quick filters for region, country, ship status or any other dimension.

17.png

4. Higher Level Filters

Dimension, measure and quick filters are very easy to use and make the process of analyzing data hassle free. However, when multiple filters are used on a large data source, processing becomes slow and inefficient. Application performance degrades with each additional filter.

The right way to begin working with a large data source is to initially filter when making a connection to the data. Once the data is filtered at this stage, any further analysis will be performed on the remaining data subset; in this manner, data processing is more efficient. These filters are called Macro filters or Higher-Level filters. Let’s apply a macro level filter on our main data source.

We can choose the “Add” option under the Filters tab in top right corner of the Data Source window.

18.png

Once we click on “Add”, Tableau opens a window which presents an option to add various filters.

19.png

Upon clicking “Add” in the Edit Data Source Filters dialogue box, we’re presented with the entire list of variables in the dataset. We can then add filters to the one we select. Let’s say we want to add a filter to the Region field and include only the Central and East region in our data.

20.png

Observe that, our dataset is filtered at the data source level. Only those data points where the region is either Central or East will be available for our analyses. Let’s turn our attention back to the sales forecast visualization that we used to understand quick filters.

21

 

In the above window, we observe options for only “Central” and “East” in the Region Filter pane. This means that our filter applied at the data source level was successful.

Hopefully after reading this article you are more aware of both the importance and variety of filters available in Tableau. However, using unnecessary filters in unorthodox ways can lead to performance degradation and impact overall productivity. Therefore, always assess if you’re adding unnecessary options to your charts and dashboards that have the potential to negatively impact performance.
