Beast Mode percentage formula gives different results on map than bar chart

user05739

I am trying to make a card that shows percentage of customers cancelling on a map. I am using the following Beast Mode formula to get the percentage of a whole:

sum(case when `Status` = 'Cancelled' then 1 end)/
count(`Status`)

When I display the results on a bar chart, I get results in the expected 0-100% range. However, if I want to put this on a map to see cancel % by state, I get values ranging from 33% to 462%. Since I am dividing a subset by the whole dataset, then this number should never go over 100%. Has anyone else had this issue on percentages not displaying correctly on a map card?

This was user error. I had a rogue sorting field that was causing the error. With that removed, everything works as it should.

Hey @user05739!

 

This is a good question that goes back to how beast mode and the map charts work.

 

Your beast mode looks correct on the graph type chart because it's utilizing the entire set of data, so while the numerator of the beastmode is using a subset of data, the denominator is counting the entire set. 

 

When you use the map chart type, the data is filtered based on what state you're looking at. Both the numerator AND the denominator are now a subset of data due to it being filtered by state. 

 

That's why you'd see abnormal results on that chart type.

 

Let me know if this makes sense of if you have any additional questions!

Hey, thanks for your help, but I'm still confused.

 

If I understand what you are saying, then in theory, the numerator should still be a subset of the denominator. See the example table below:

State	Status
NC	Active
CO	Active
GA	Cancelled
CO	Cancelled
CO	Active
CO	Active

 

In this case, Colorado should have 25% cancels and never go above 100% because you cannot have more cancels than you have records. The only instance I would see that could change this is if the numerator were counting all Cancels (2 total; 1 for GA, 1 for CO) over the denominator for only CO. However, I would imagine that Domo is filtering all records by state.

 

Additionally, if my bar graph is divided by state, then the two of these should be using the same logic for calculation, correct?
