Project Task Completion - Complete and Remaining Pie Chart

AAL ✭✭✭✭

Hi Smartsheet Team,

a. Can you tell me how I can make the following Project Task Completion chart? In the Smartsheet, what column or tasks do I have to select to make this chart?

I also want to ask if I post something here but then I find the solution and want to cancel my post. Do you know where I can delete the post?
