Basically use a tablix next to your chart.

Question
I'm building report using SSRS 2008 (Report builder 3.0)
I'm afraid I know the answer but still wondering if there is a way to link to Drill down report from the Legend area ? I know I can do it from the data labels.
Did anyone succeeded to crate some workarounds?
