How to show cumulative count month-wise in Performance Analytics?

[Deebika]

I am trying to create a monthly cumulative count in ServiceNow Performance Analytics.

My requirement is:

• January monthly count = 30 → Cumulative = 30
• February monthly count = 20 → Cumulative = 50
• March monthly count = 10 → Cumulative = 60

So, each month should include the previous month's cumulative value plus the current month's count.

I already have an Automated Indicator that provides the monthly count based on Current Phase Start Date.

Could you please advise how I can configure the cumulative/running total month-wise in Performance Analytics?

Should this be achieved using a Time Series, Formula Indicator, or another configuration?

Thanks
