Build a Power BI Pop Out Slicer

Save more screen for your team! The pop out slicer panel is a perfect way to conserve space while building out your dashboard (i.e., reports) in Power BI desktop. It really is a slick feature that allows you to conserve limited reporting space by hiding your slicers until the user presses a button to reveal your data filtering options.

In this video you can watch me build out the slicer panel step by step using bookmarks, selection panel and buttons.

  • Bookmarks are a configured view of a report page, including filters, slicers, and the state of visuals.
  • The selection panel allows you to show and hide current objects on the current report page.
  • Buttons enable users to hover, click, and further interact with Power BI content

How to Drill Through in Power BI

One of the great options available in Power BI is the capability to “drill through” to another report page. In this manner you can focus on a particular entity such as a customer, internal division, supplier or any other dimension of importance.

Different users have different data needs. When designing a dashboard typically the Key Performance Indicators (KPIs) are aggregated at a high level on the initial visualization. This offers executives and management types a “bird’s eye view” of performance.

Personally, I am a fan of BANs (look up the term in a dashboard design context if you are not familiar) when I want to highlight key takeaways.

BANs

Subsequent lower level dashboard pages can offer analysts and others the ability to either explore data with additional interactivity or simply display a static detailed report. The point is to start at a high level and allow your user to drill to a more granular level of data.

In this video I demonstrate the use of the drill through functionality in Power BI. In this scenario, you are the Chief Supply Chain officer trying to gauge your Perfect Order Percentage KPI for several internal divisions. When it’s time to sit down with your four division mangers to discuss their performance on this metric, you want the ability to start at a high level and then drill through to a static report based upon their respective internal divisions or on a specific shipping error.

Drill through on “In Full Delivery” error category

Do not try and cram every visualization, chart, table or gauge under the sun into a dashboard! Take advantage of drill through functionality and tailor your data presentation for specific user groups. This general concept applies to any data visualization tool, but if you’re using Power BI then this video will help you understand the specific steps required to enable drill through functionality.

I’m frequently questioned where I obtain mock data for my scenarios. My secret source is mockaroo.com which is a great starting point for developing test data.

As always, do great things with your data.

How to Create a Dashboard in Tableau

I took the time to produce a dashboard series that would get a relatively new Tableau user up to speed in very little time. I put together the “Goldilocks” videos I wish I had when I was a novice; not too short but long enough to hammer the concepts home.

In the first video, I dive head first into constructing four basic charts that I believe every data user should know how to put together. You will watch me demonstrate how to put together the following charts:

Line Chart with Forecast

Tableau Dashboard Line Chart

The shaded area is a time series forecast predicting the number of orders for the year 2020.

Map

Tableau Dashboard Map

Heat Map

Bar Chart

Tableau Dashboard Bar Chart

In the second video, I’ll cover the layout and formatting of the dashboard, as well as adding a little interactivity. When the user hovers the cursor over the Line Chart, all of the other charts will update to reflect the number of orders represented since the selected month and year.

Tableau Bar Chart: Combining Small Values

In this video we’ll learn how to build a bar chart visualization that combines values below a certain threshold into an “OTHER” bucket. This technique is very useful when limiting the number of bars to show on your visualization while not losing sight of all the smaller values.

  • Using standard Tableau Superstore data, we’ll calculate the percentage of sales that are generated by each individual state.
  • We’ll then use a parameter to set a percentage threshold where all states below this percentage will be combined.
  • This technique also requires the use of sets and Fixed LODs.

This technique allows us to combine all states below a certain threshold (e.g., 2%) into one single bar chart showing a combined 24%.

I have to give credit where credit is due to Ann Jackson for sharing this technique at TC19!

Build a Stacked Donut Chart in Tableau

Have you ever wanted to stack 4 pie charts on top of each other to build a visual? Let’s have some fun building out a stacked donut chart or a “TrailBlazer” chart as I call it due to its likeness to a particular NBA team’s logo.

Stacked Donut Chart Thumb

Portland Trailblazers anyone?

Stacked Donut vs Trailblazer

In order to build out this chart I used an innovative technique shared by Simon Runc on the Tableau forums. Feel free to check out that post here.

Using Tableau’s Sample Superstore Data, Simon came up with an innovative use of the INDEX() function and the Size functionality to create three different pie charts that each show a respective percentage of a measure (in this case Sales) to the Total amount of the measure.

For example, the chart highlights in red the percentage of Consumer Sales as a percentage of all segment sales (i.e., Consumer + Corporate + Home Office). The grey portions represent all other sales, other than the segment of interest.

The trick to this approach is using the Index function to create a pie chart per segment. For example Consumer is assigned a value of 1, Corporate a value of 2 and Home Office is assigned 3. When the INDEX() value is placed on size, the three different charts are assigned sizes where one is slightly larger than the next.

Stacked Donut Raw 2

With a little division and axis customization, the three segments are placed on top of each other to provide a stacked pie chart effect. The hole is courtesy of the standard methodology for creating a donut chart which involves a dual axis.

It makes much more sense when you see it in action so make sure to watch the video!

Here is an example of the raw stacked donut chart before the “TrailBlazer” formatting.

Select Random Sample Values and Rows using Excel

In this video I help you solve the dual problems of selecting a random value from an Excel list and selecting a number of random rows from a range of data in Excel. At times when I am generating a data-set to use in my video tutorials, I want to select a random selection of rows. Typically, because my data values are clumped together and are too similar to the data on preceding and subsequent rows.

SELECTING A RANDOM VALUE FROM A LIST

Enter three Excel formulas to save the day for selecting a random value from a list:

  • ROWS()
    • Returns the number of rows in a reference or array.
  • RANDBETWEEN()
    • Returns a random integer number between the numbers you specify. A new random integer number is returned every time the worksheet is calculated.
  • INDEX()
    • The INDEX function returns a value or the reference to a value from within a table or range.

Randow Row in Excel Blog Screenshot

  1. In the screenshot above notice that the ROWS() function returns the value of 20, which corresponds to the number of names listed in the cell range of A6 to A25.
  2. The RANDBETWEEN() function generated a random number between 1 and the value returned from ROWS() (i.e., 20). In this case, RANDBETWEEN() combined with ROWS() returned a value of 3.
  3. By combining the results from the first 2 functions, the INDEX() function searches our list and returns the value of the 3rd cell in the list  (i.e., Flor McCard) because the RANDBETWEEN() function returned a value of 3.

When we put it all together it looks like the following:

=INDEX($A$6:$A$25,RANDBETWEEN(1,ROWS($A$6:$A$25)))

I choose to use the absolute cell reference notation with dollar signs although in this case it is not necessary since we are not copying our results to other cells.

SELECTING RANDOM ROWS FROM A LIST

We’ll only use 1 Excel formula to save the day for selecting random rows from a range:

  • RAND()
    • RAND() returns an evenly distributed random real number greater than or equal to 0 and less than 1. A new random real number is returned every time the worksheet is calculated.

By placing the RAND() function in a column co-located with your data, you will assign a random number to each row in your data-set or range.

Once that is done, all you have to do is sort your data by the RAND() column and then select however many rows you need. It’s that simple!

If you are like me, you probably need to see it in action to get a better understanding. Check out the video above and if you learned something, please go ahead and like it on my Youtube channel!

Build a Tableau Parameter Action Dashboard

This video is inspired by Filippos Lymperopoulos who has a great article on parameter action concatenation. Definitely check out his article here. I am a hands on person who learns from building and sharing, therefore I put together this video to explore, tweak and hammer home the concept.

In this video we’ll build a Sales Analysis dashboard in Tableau using Parameter Actions and the Concatenation Aggregation functionality. The great thing about this tip is that you can use it across multiple data sources. This is a must see!

This approach relies upon the use of two different data connections. In this manner our data tables are completely un-joined without an established relationship. We have a data-set comprised of a customer list and one comprised of customer transactions across three years.

The key to linking the data sets together relies upon the following calculated field which creates a de-facto set that we can use to highlight customer purchases:

Tableau Concat Calc Field

When we setup a concatenation parameter action on our dashboard, the very act of selecting a [Customer Name] will add that Customer Name to the parameter named [Selected Customer]. This will cause all selected customers to resolve to TRUE, which allows highlighting of the sales bar charts related to the user selected customers.

Tableau Concat Parameter Action Thumb1

In the screenshot above, notice the selected [Customer Name] values on the left hand side are also concatenated together at the bottom of the dashboard (i.e., Franciso Hernandez, Jose Garcia, and Terrye Marchi). All of their respective purchases are also highlighted in the middle of the dashboard.

Tableau Concat Calc Field Label

The above calculated field is used to only show the [QTY] purchased for the user selected customer and is placed on the bar chart label.
