Waffles = 😋
Power BI = ⚡
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.
Waffle charts in Power BI - Step by step tutorial
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:
Numbers table for waffle chart
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.

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.
Your thoughts...
I had such fun creating this chart in Power BI. What do you think about Waffle Charts? Are you planning to m(b)ake a few for next report? Share your thoughts in comments below.

Pivot Table will involve manual intervention; hence I prefer to use the 'countif remove duplicate trick' along with 'text sorting formula trick; then using the offset with len to name the final range for validation.
if using the pivot table, set the sort to Ascending, so the list in the validation cell comes back alphabetically.
Hui: Brillant neat idea.
Vipul: I am intrigued by what you are saying. Please is it possible to show us how it can be done, because as u said Hui's method requires user intervention.
Thks to PHD and all

Table names dont work directly inside Data validation.
You will have to define a name and point it to the table name and then use the name inside validation
Eg MyClient : Refers to :=Table1[Client]
And then in the list validation say = MyClient
Kieranz,
Pls download the sample here http://cid-e98339d969073094.skydrive.live.com/self.aspx/.Public/data-validation-unsorted-list-example.xls
Off course there are many other ways of doing the same and integrating the formulae in multiple columns into one.
Pls refer to column FGHI in that file. Cell G4 is where my validation is.
Vipul:
Many thks, will study it latter.

[...] to chandoo for the idea of getting unique list using Pivot tables. What we do is that create a pivot table [...]
@Vipul:
Thanks, that was awesome! 🙂
@Playercharlie Happy to hear that 🙂
Great contribution, Hui. Solved a problem of many years!
Thanks to you, A LOT
Hi Hui,
Greeting
hope you are doing well.
I'm interested to send you a private vba excel file which i need to show detail of pivot in new workbook instead of showing in same workbook as new sheet.
Please contact me on muhammed.ye@gmail.com
Best Regards
