How to create a pie chart to display the return in % per segment. But when I do, size is the same for all. how to correct

This is a common problem with the pie chart. Usually, what we do is show the percentage contribution by each category. and to differentiate between the different areas of the pie chart we put the category into the color shelf. but as we know, the pie chart also depends on the sizes and so, the size remains the same for all the segments. To prevent this, you can put the measure into the size self in the marks card.
