Dynamically change the Dimension of a chart

Hi All,

I am new to BEx Design studio. i have a requirement where i have to show a pie chart based on the dimension selected in the Drop down.

Ex: 1st Pie chart - Headcount by Selected Dimension such Employee group.

2nd Pie chart - Headcount by Employee sub group.

3rd pie chart - Headcount by Worker Type.

4th pie chart - Headcount by Age Group.

Drop down has entries - Employee group, Employee Sub group,Worker type and Age group.

Can i achieve using one pie chart to get the above solution. if so, can you guide me.

Thanks in advance.
