Agree with others - this should be in vanilla Anki. Simple with useful functionality.

I have edited some values to customize the graph. I wanted to narrow the range of ease shown to max = 260, min = 130. This is super easy to do. Harder was figuring out how to get it to display more graphs for ease at 5% intervals instead of the default 10%. To do that, I replaced the line with "select round(factor/100)*10 as int from cards" and changed it to "select round(factor/50)*5 as int from cards" - not too difficult (but also required changing width of bars from 6px to 4px). The one thing I can't figure out how to do is to change the X-axis labels to show every 10 percentage points instead of 20. Any suggestions?

Very good. Would be nice to be able to see the plots separately for "learning", "young", and "mature" cards.
