I found that bar chart is build based on the data at details section.. how to build bar chart base on group header section..?

Because i hv to filter out the data at bar chart by group selection:

Sum ({@value1}, {ID_NO}) > 0.00 and
Sum ({@value2}, {ID_NO}) = 0.00

 

Lets say the total data after group filtering is 10 only, but the bar chart still display 15, which without group filtering.. I need to display 10 bar only.. after the filtering..

 

pls help. thanks..
