Boxplot xlim does not match given x values for by
I have a boxplot by a boolean variable. It looks like DataFrame.boxplot changes the x values for the plotting however from 0 and 1. I'd like to add a jittered scatterplot on top of it, but I can't get them to line up because of this change. Still looking for where this actually happens.

Are there cases where using 0, 1, 2, 3, etc. values for the groups doesn't make sense? I can see a case for Categorical types but then you should also know the underlying integer representation right?

[_Edit_: It occurred to me that this may be matplotlib behavior and I'm just trying to do this the wrong way.]
