Calculating a KPI based on value displayed in two visuals

[sfagan55]

Hey all!  Relatively new to PowerBI and I've run across a problem I haven't been able to find a solution to.  I have a report that displays a quantity of inspected items versus a quantity of defective items.  Unfortunately, the data for the total inspected items is in one source, and the data for the defectives is in another source.  When the two are linked together, filtering the data for the defective items will ONLY display data from the inspected items that were discovered to have a defect.  I have two separate visuals on my report which are filtered independently and show the correct values.  My question is this: is there a formula I can use to show a value based on addition/subtraction/multiplication/division of the displayed value in two separate visuals?

Hi @sfagan55 

Do you mean you'd like to apply the addition/subtraction/multiplication/division on several visuals separately? 

You might check with the what-if parameter:

I should have started by saying that the visuals are both tables.  Column A in each identifies the type of defect, while Column B in Visual 1 displays the total number of inspections for that type of defect, while Column B in Visual 2 displays the total occurences of defect.  There aren't any filters in Visual 1 because I need the total quantity of inspections performed.  There are multiple filters on Visual 2 because it displays first pass yield.  If I apply the same filters to both visuals, then my total quantity inspected reduces to only the inspections where defects were discovered (because with the filters and links between tables defined, that's all it can recognize).  The number I need is the value in Column B of Visual 2 divided by the value in Column B of Visual 1 (defectives as a percent of total inspections).  I don't need the math to span multiple visuals, just to give me an aggregate value of the two visuals.

Thank you both for your assistance and I apologize I can't share the visual; it has proprietary data in it at the moment.  If I can strip it out, I'll share something.

Depending on your visuals, you may be able to refer directly to the values being displayed by your visual in a DAX measure and load them into variables, then compare the variables to get your result.

Or you may be to recreate the filters on the visuals in your DAX measure to get the 2 values you want to compare.

If you can share a sample power bi file we can be more specific.
