Bug report

Bug summary

Docstring for plt.bar:

matplotlib.pyplot.bar(left, height, width=0.8, bottom=None, hold=None, data=None, **kwargs)
Make a bar plot.

Make a bar plot with rectangles bounded by:

left, left + width, bottom, bottom + height
(left, right, bottom and top edges)

However, "left" is in fact the center value of the resulting bars.

Code for reproduction

# Paste your code here##importnumpyasnpimportmatplotlib.pyplotaspltlefts=np.asarray((0,100,200,300,400))plt.bar(left=lefts,height=lefts,width=100)plt.bar(left=lefts,height=lefts,width=75)plt.bar(left=lefts,height=lefts,width=50)plt.bar(left=lefts,height=lefts,width=25)

Actual outcome

# If applicable, paste the console output here##

Expected outcome
Bars should be left-aligned to the "left" value.
As the attached plot shows: Bars are centered on "left" value, and not left-aligned to it.
