How to show % of completed steps in a Pie Chart

Is there a way to use the Pie Chart element, to calculate the number of completed steps in a user’s profile?

That is, let’s say there are 10 fields and only 5 are completed. Then the pie chart is 50% complete

The Line Chart element from what I can see, doesn’t accept a single integer, it’s looking for a list of Users but I just want data from 1 user, which is the Current User

For clarity, I want to compare the Current Users stats against themselves and have a total amount be the number of fields the user has vs the number of fields that are filled.

Also, the solution needs to be dynamic as a User can remove and fill an input at any time.
