I wonder if there is a documented behavior when making a barplot
with datetimes (more precisely pandas DatetimeIndex) as the x
I've pasted an example below with matplotlib 2.0 and pandas
In this experiment, it seems that the width of the bars is
interpreted as a number of days, so if I want to plot monthly data
without blanks, I have to put width = 31. So my question is: is
it a reliable behavior that the bar width is a number of days
when working with a DatetimeIndex?
Notice that it is not coherent with pandas behavior: when
addiding +1 on a monthly datetime index it adds on month.
Also, with the default width value (0.8), some of the bars are
not visible and I don't understand why, but maybe it's a separate
