Dashed line step plot

Community matplotlib-users

Hello,

Can someone confirm me if this creates a dashed line for a simple step plot?

this is fine

plt.plot(range(10), “g–”)

plots solid line!

plt.step(range(10), “g–”)

Thanks,

I get a solid line for plt.step like you do.

MPL 1.0.0, SVN revision 8657.

My version is v8624. Looks like a bug to me.

Not a bug, but a “feature”. In step(), the ‘linestyle’ kwarg gets over-ridden with a value of ‘steps-’ + kwargs[‘where’].

Hard to interpret that way at the first look. This does what I want:

plt.plot(range(10), ‘g–’, drawstyle=‘steps-mid’)

I’ll admit that I am not very familiar with how these step plots are done. Maybe it should be the ‘drawstyle’ kwarg that should be over-riden, not ‘linestyle’?

This seems like more reasonable to me. When I update /matplotlib/lib/axes.py:

kwargs[‘linestyle’] = ‘steps-’ + where → kwargs[‘drawstyle’] = ‘steps-’ + where

then I get the expected behavior.
