JSON Input arithmetic

Hello.

I need help with JSON input.
help me figure out how to make a line graph

On the graph, display a value equal to (C1-C2) / C2, where:

C1 = Number of calls for the getPersonInfo time period
C2 = Number of calls for the sync method time period

on them I created in one visualization, two filters.

Now I need to make (C1-C2) / C2 through JSON input

Hello,

Can you please use time series visual builder and math aggregations on it?
