How to prepare a pie chart with reference to bar chart?

Hi all,

In attached file, sheet Graph contains a bar graph which is linked to table in sheet Ticket Count. With reference to same table, i want a pie chart which should show data for Months i.e Column A of sheet sheet Ticket Count and total counts of Column G (Incident) and Column H (Request) as given in cells G369 and H369.

For example, when i select March in slicer in sheet Ticket Count, the pie chart should show count of Incidents as 60 and Requests as 90.

Can someone please help?

Perfect. Thanks a ton.
