Waffle chart in Power BI = 😍

So let’s make some waffle charts in Power BI. They can be a fun way to show single numbers in your dashboards.

Step 0: Create the necessary measure to visualize

Let’s say you want to visualize a measure [Preferred Value] in the waffle chart.

Step 1: Create a numbers table

To make waffles, we need flour, salt, baking powder and sugar. I am kidding, we won’t be baking any real ones here. We just need a disconnected table to make waffles. 

Our table needs to have numbers 1 to 100, row & column values. You can either type one in Excel and bring it over or create one in Power Query. The final table shall look like this:

Index has numbers 1 to 100, Row has 1 ten times, 2 ten times... and Col has numbers 1 to 10 repeated.

You can create this in Excel or Make it in Power Query too.

Step 2: Add measure to harvest the number

Create a simple [number] measure with the formula =SUM(Numbers[Index]). This will simply return Index value when used in a visual with all row & col combinations.

Step 3: Add measure to show Waffle Filled portion

Now that we have both [preferred value] and [number] measures, let’s create the final one. I call it [Waffle Filled]. 

[Waffle Filled]:=IF([Preferred Value]<[Number],BLANK(),1)

This measure simply returns 1 or BLANK() depending on the values. 

Step 4: Let’s make that waffle – Insert a Scatter Chart

Ok, we have prepped enough. The iron is hot, let's whip up the waffle. 

  • Insert a scatter chart
  • Add Numbers[Row] to Y axis
  • Add Numbers[Col] to X axis
  • Add [Waffle Filled] to size
  • Click on X axis and choose "Do not summarize" option. Do the same for Y axis too.

hmm, that's not a waffle

Not edible or comparable...

Step 5: Format the waffle chart

Don’t freak out. This is not a radiation infested waffle. It just needs a bit of whacking around the edges. 

  • Fix the axis: Set axis limits from 0.5 to 10.5 for both vertical (Y) and horizontal (X) axis.

  • Change the shape: Go to shapes format setting of the scatter chart and change the shape to square. Also set the size to -20 (try a few different values to see which works for you)
  • Remove axis, axis labels, grid lines and anything else you don’t want.

Voila, our waffle is ready to eat.

Don't go crazy with waffles

Just as too many waffles can lead to diabetes, excessive usage of this visual can make your reports hard to read. Just use one or two to get the conversation going. If you end up making a dozen of them, then you have gone too far. Consider a stacked column chart or something else.

Learn how to calculate weighted averages in excel using formulas. In this article we will learn what a weighted average is and how to Excel’s SUMPRODUCT formula to calculate weighted average / weighted mean.

What is weighted average?

Wikipedia defines weighted average as, “The weighted mean is similar to an arithmetic mean …, where instead of each of the data points contributing equally to the final average, some data points contribute more than others.”

Calculating weighted averages in excel is not straight forward as there is no built-in formula. But we can use SUMPRODUCT formula to easily calculate them. Read on to find out how.

    I had a go at the yummy waffle, but cannot change the shape percentage to a negative 15% like you did. Therefore my waffle does not look like a waffle... Please help. Kind regards, Mark. PS you are awesome.
