Drill through on same report

[simi]

ALL,

I have a report page, which has two prompts and staged bar char and List.  Here the bar chart is drillable.  When i click on the chart , then chart should should drill through as show the detail on the same page. the corresponding detail should display in list.

I have achieved the above requirements. what i need is when i click on the chart , the report goes to the detail. Again i should go to the original state. for that i have created a drill through link . But this link disabled when i click on the bar chart

How do i have Button/link to go to the initial state of the report?
