Query based pie charts in Azure DevOps - how do I display a percentage rather than a count?

Hi,

I created several charts to track the progress of bugs and test cases. I will use the following two as examples:

1. Open Bugs by State: please reference attached - this chart shows the count of open bugs in each state.

2. Test Case Results by State: please reference attached - this chart shows all the test cases created, pivoted by state.

Is there a way to display percentages for each pie slice, rather than the count? For example, in the Open Bugs by State, rather than showing Open = 18, can I display "72%" (18/25)? Right now when I configure the chart, I see the "Aggregation" option, but this only allows me to choose "Count". Do I need to update my queries somehow to get a %?

Thank you for the assistance!
