Conditional Chart - Set Analysis

[#1]

Hello,

I want to show a chart only if the value of Amount_Online (my fact) is > 0. So I'm writing a expression to introduce on Conditional Tab of Chart.

How I can right this expression correctly:

= Count({<(SUM(Amount_Online)>0) >} ID_Consumer)

Thanks!

Try =If(sum(Amount_Online)>0,1,0)
