Power User Curve - L30 - Frequency of Sessions

Hi folks!

Has anyone tried setting up a power user curve as defined here? https://andrewchen.com/power-user-curve/

Basically a graph of “Total Active Days” on the x-axis and “% of Users” on the y-axis. 

I’m a bit new to this, but I’m guessing it’s a sum of the number of times they had a session that month (or week) or the frequency of times they had a session that month? 

I can’t find a way to set this up on Heap though. Here’s what I’ve tried

Retention Analysis: From Session to Session (the problem is that it’s sequential rather than a sum. ie. it looks at how long it took for them to come back 2 days vs 30 days instead of total number of times they were back)

Usage over Time: Count Unique of Sessions, Grouped by “Users Who Have Done a Count of Session” (the problem is that it does a sum for each date instead of a rolling 7 or 30 day count)

Funnel: Page View to Page View, Grouped by “Users Who Have Done a Count of Session

Any other ideas?
