I didn't get there, but maybe this can give some ideas.
Using the method described here:
was able to get the Program Combinations.
With the help of a filter, was able to get a count of the number of accounts per bin.
However, it is proving to be tricky to get the percent.
Will need to work on the that more.
Open to suggestions from the community.
