[matplotlib-devel] Bug in pyplot.hist when using histtype="step"

[Detlef M. (IKP) <det...@ki...>]

Hi all,

there seems to be a bug in in pyplot.hist when using histtype="step".

I am plotting the attached data to a histogram (see 1.png). In this case 
I set the limits on the y axis manually.

When I don't do this (let the hist function choose the limits), I get 
the picture in the file 2.png. Only the highest bin is drawn. To be 
exact, ymin=second highest value, ymax=highest value.

To solve this, I suggest the patch in the attachment.

I also removed the for loop here, because I don't see why 0 height bins 
should be filtered out (but this is just a suggestion).


cheers,

Detlef Maurel
