Display Table Column Values in Pie Chart

Hi ,

   I am having problem with pie chart data binding.....

In the above image i am doing pie chart binding with local json data but i need to bind data to pie chart from table, like if i select zone in drop down values i will get pie chart binding from table zone column.

if i select State in drop down values i will get pie chart binding from table Statecolumn. .....

After that if i select a section in pie chart i.e., if i select "South " as a section, only south records should display in the table.

Please help me on this.
