plotting years and months

Community matplotlib-users

This is such a noob question but I can't seem to find the answer anywhere. I
have a certain amount of something per month which I want to display on the
y axis, I want the x axis to show years and months, i.e. it runs from 2003
to 2009. I have no problem with the python side, just the plotting side. How
do I do it?

matplotlib can plot native datetime objects, so if dates is a list of
datetimes, and vals is a list of values, you can:

  ax.plot(dates, vals)

See also these code examples:

and the dates API documentation:
