>i have a report  with column names 'region','revenue','year'
>in same report i have a chart.
>when i clicked on region column i will drill down to country
>when i clicked on country i will get states

in the same same i want to see my chart.
eg:>if im in region, chart should show in  region wise
>if im in country it should show country wise chart
etc......

how can i change my chart dynamically based on 'region' column
