I updated the plot_dates docstring in svn to point to matplotlib.dates > http://matplotlib.sourceforge.net/api/dates_api.html > > They are there in the diagram on top, but don't seem to be on the page. That is odd -- any sphinx gurus have any idea why these are not being picked up by the automodule code? >>> note: I'm trying to do this for the x axis of a quiver plot, which >>> doesn't seem to support passing in dates directly. > > by the way, is that a bug that should be tracked down and fixed? Not all of the methods currently support direct date/unit plotting, but we do try to extend support when we have reported failures, so if you post a script which exposes the problem I'll try and fix it. > However, in this case, I'm trying to write method that takes an axes object, > and plots to that -- how can I do this without the figure reference? Most mpl objects have a reference to their parent, so you can walk up the containment hierarchy, eg line.axes.figure.canvas so in your case ax.figure.autofmt_xdate() but note that autofmt_xdate is designed to work for subplots with only one column, not in the case of general axes configurations, so calling this from an axes in a method that does not know how the axes are layed out does not make sense. But you can do the main part yourself for label in ax.get_xticklabels(): label.set_rotation(30) label.set_horizontalalignment('right') > But it does work well if you apply it to the figure after my plotting > routines. That is the best place to apply it, because there you know the subplot layout is suitable for the call.
