Show/Hide chart on selecting value on first chart

Hi Experts,

I have a requirement where I am having 3 Pie charts, let say C1, C2 and C3. C1chart has element linking to C2 and C3. In C1 we have 5 values let say v1,v2,v3,v4,v5. I want when user click on Chart C1's v2 value then I have to show C2 chart else on any other value clicked on Chart C1 hide C2 and C3 will be shown all the time.

Please help me in resolving it.

Thanks,
