We created the chart in a SSRS report based on SSAS cube.
When we clicked on one of the areas in the chart, we were invoking the same report but were unable to pass proper values – [Dim Abc].[Attribute Xyz].&[Value1].
The key is to create a “calculated member“.
In dataset Query Designer, right click on “Calculated Members” pane and select “New Calculated Member”.
The expression to use is:
MEMBERTOSTR([Dim Abc].[Attribute Xyz]).
Add this newly created Calculated Member in the result of the datasets by drag and dropping.
Use the above created field for Chart data (in our case Category Groups).
