Drill down on Charts(Graphs)

Hi,

I have three level hierarchies Country, State and customer for drill down

Country should be shown in bar chart.

When report is opend first time, this bar chart will be displayed.

Now only one chart is showing for coutry.

I will start drill down.

If I click on the bar(coutry bar chart) , below of the bar chart, map chart should be displayed for state.

If I click on map chart(state map chart) , below of the map chart, line chart should be displayed for customer.

Now there are three charts bar, map and line after drill down.

How to achieve these please let me know.

Thanks and Regards,

Manjunath
