How to create cumulative line chart?

Hallo!
I create a line chart with a date field on x axis and a string field on y axis counting the distinct times each value of the string field appears per date. I would like to make this graph a cumulative line chart. Ideally, it should show the number of distinct values of the string field appearing per date and as the line moves forward sum up these distinct values to show the trend (increase or drop) in these distinct values. Is this possible?

Hi @Fotis_flex

Hi @ErikG . Thanks for this fast response. Yes exactly, this seems optimal. I already tried the Clustered bar combo chart but I don’t get the cumulative bars as expected (?)

I used runningSum(count(Change),[Date1 ASC])
