multiple constraints pie chart

I need to make 3 pie charts based upon well name.
Chart 1: Test 1
Chart 2: Test 2
Chart 3: Test 3
Now the names will change over time and is set up on a drop down from Reference tab.
The catagory is NPT Party and the Duration is the actual chart.
The chart title will be Test 1, Test 2, Test 3 with this linked to change over time.
If anyone can help make this possible i want to thank you a million.

Please take a moment to re-read forum rule #1 and then amend your thread title to something that better explains your problem. Changing your thread title is not optional, which means you must change it. Thanks!

• Use concise, accurate thread titles.
  
• Your post title should describe your problem, not your anticipated solution.
• Use terms appropriate to a Google search - poor thread titles, like Please Help, Urgent, Need Help, Formula Problem, Code Problem, and Need Advice tell us nothing.
• Responding to a request to change your thread title by doing so is mandatory.

To change a title go to your first post, click EDIT then Go Advanced and change your title.

No help to be offered, please, until the OP complies with this request.

That's a bit better - thanks.
