Incremental Custom Time Series panel

Hi,
I need to create an incremental time series panel that uses default Prometheus Datasource. Incremental means that value for given hour is equal to value of previous hour plus current hour value.
I prefer not to write a new custom datasource and stay with Prometheus so the question is:
Is it possible to create a new grafana panel that will extend default TimeSeries with incremental value calculation? Or is it possible to achieve this without writing new panel but just by properly configure TimeSeries?

Much Thanks,
Adam

Hi - this sounds like you’d just need a cumulative transformation Transform data | Grafana documentation?
