Addresses issue #320. The example is @pelson's, I just added some comments. Also, Gaussians look pretty.
Add Phil Elson's percentage histogram example
Seems fine. Did you look into the potential of using a scale? I've never done it that way, but it seems that (in my head at least) that would be a viable solution too.
I'm happy enough with this approach though. +1
I did not. I thought yours was good enough! :)
It might be slightly better if the formatter added a percent symbol at the end, but otherwise, I think this is good to go.
Milestoning this to 1.2.x since #320 is also.
Add a percent symbol to tick labels
Got to be careful when latex is involved.
So yeah, it's a bit more fiddly to use the percent symbol with latex.
