Name - GroupName - Score
GroupName is an array: {G1, G2, G3}
I send this data source to my report and want to show sum and percent of all scores of each group in two Pie Chart to user:
Pie Chart 1:
Pie Chart 2:
After a day i recognized how to do this.
In Stimulsoft reports you can create a datasource of another datasource just in New Data Source select Data from Other Data Source and by aggregate functions create your own columns.
