fill_between with drawstyle steps?

Community matplotlib-users

Hello ExPyrts;

I'm trying to do a fill-between part of a spectrum and its continuum
value. I would strongly prefer the drawstyle to be steps, since each
data point represents a bin (or pixel, to be precise).

Attached is a picture illustrating my problem.

Isn't it possible to fill between my step graph and the hline?

Cheers;

Emil

I haven't found that capability built-in, but you could do it if you construct
the steps yourself. In lines.py in the matplotlib source, look at the
_draw_steps_pre and similar methods of the Line2D class to see how the
coordinates of the stepped path are constructed. You could then pass those
coordinates to fill_between.
