Comment:

 Glad to hear you like this plot! I don't know if there's a name for it. I
 only know that drawing it required quite a bit of code for extracting
 values from PostgreSQL. There are functions for quantiles, but not for the
 new high/low values without outliers. There's also no single function in
 R/ggplot2 to draw this graph. So, even if this graph has been made before,
 it might not have made its way into the statistics tools yet.

 Please review [https://gitweb.torproject.org/user/karsten/metrics-
 web.git/commit/?h=task-29773&id=fd251d6c69efeb3d548f915cc40e001e89c1f41f
 commit fd251d6 in my task-29773 branch].

 (Earlier today I considered preparing the patch for #29772, but I'll
 instead work on another patch, because any revisions to this patch would
 also have to be made to #29772, and we shouldn't duplicate effort if we
 can avoid it.)
