Hi @shreyad
I believe whole Pie is considered as 100% in which each value takes some percentage by calculating its quantity on the whole.
bringing pieces from individual queries should not be the case.
Thanks
How do your individual queries look like? You can combine all your individual queries into one search and then run statistics on the result set to generate a piechart
Eg:
mysearch1 |table field1 count | append [mysearch2 |table field1 count ] | append [mysearch3 |table field1 count] | stats sum(count) by field1
