问题
Why am I getting this error in my chart? (Chart Image)
I am using this expression in the chart:
Series:
=Sum(Fields!Mins_Att.Value)/Sum(Fields!Mins_Poss.Value)
Series 1:
=Sum(Fields!Mins_Att.Value,
"Chart2_CategoryGroup2")/Sum(Fields!Mins_Poss.Value, "Chart2_CategoryGroup2")
and I am getting this error:
The Y expression for the Chart has a scope parameter that is not valid for an aggregate function. The scope parameter must be set to a string constant that is equal the name of group, data region or name of dataset.
回答1:
The scope of "Chart2_CategoryGroup2" doesn't exist in the report.
