reporting-services - 是什么导致了我的 SSRS 图表中的范围参数错误？

Question

为什么我的图表中出现此错误？ ( Chart Image )

我在图表中使用这个表达式:

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")

我收到此错误:

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.

Answer 1

报告中不存在“Chart2_CategoryGroup2”的范围。
