Compounded Expression in Line Chart

[nwilliams]

Hi,

I'm trying to create a line chart that has a compounded expression.  For example, I have the following data

Jan - 10

Feb - 9

Mar - 11

Apr - 15

May - 5

What I want to show in the chart are the following values

Jan - 10

Feb - 19

Mar = 30

Apr - 45

May - 50

So this will effectively create a line that always curves up.  Any ideas how this can be achieved?

Enable the Full Accumulation option for the expression. Or use something like rangesum(above(sum(Value),0,rowno())) as expression.
