How do I create a donut chart that shows a percentage of completed items out of a total number?

I am trying to make a donut visual. I have 34 items in total, and 19 completed out of those 34. How do I make this into a donut chart? When I have done it previously, I either get a percentage of the 34 + 19 total count, or I can't change the keyHow I want it to look but with different titles at the top for the 2 sections as shown on other donutData fields for incorrect donut, but correct title settingsData fields for correct donut, but incorrect titles
