I have a running total that I want to graph but I can't make it work. The running total works fine in a Table. My dataset gathers Quantity by Year.
If I set the Series of the graph to =RunningValue(Fields!Qty.Value,sum"RunningTotal") the graph just shows one column wich is the value of the running total for the last Year. As soon as I add Year to the Category of the graph I get Scope errors.
"The DataPoint expression for the chart has a scope parameter this is not valid for RunningValue, RowNumber or Previous......"
What I need to show is the Runing Total of Qty by Year - just like the Table shows. How can I do this?
