Bug report

Bug summary

Automatic placing of legend seems to be not working with histograms of typestep*. If I am correct, this is a new entry in the long list of current issues with legend ^^.

Code for reproduction

importmatplotlib.pyplotasplthist_types= ('bar','barstacked','step','stepfilled')fig,axs=plt.subplots(nrows=len(hist_types),num="test")forax,htinzip(axs.flat,hist_types):ax.set_title(ht)ax.hist([0]+5*[9],bins=range(10),label=f"This is a label",histtype=ht)ax.legend(loc="best")fig.tight_layout()#fig.savefig(fig.get_label() + ".png")

Actual outcome

Matplotlib 2.1

Expected outcome

The same auto-position of the legend on each subplot, i.e.upper left, whatever is the histogram style.

Matplotlib version

• Operating system: GNU/Linux (Fedora 26)
• Matplotlib version: 2.1 from conda (also test “successfully” with master)
• Matplotlib backend (print(matplotlib.get_backend())): Qt5Agg
• Python version: 3.6.3 from conda
• Jupyter version (if applicable): X
• Other libraries: X

FWIW, I tried the above snippet on Matplotlib 1.5.0 and the result is similar.

Edit: tweaked a bit the snippet to be Matplotlib v1.5.x-compliant.
