Re: [Matplotlib-users] Where are AutoDateLocator and AutoDateFormatter?

mpl.ticker.AutoDateLocator

Where might I find these now? They don't seem to be in matplotlib.ticker
or matplotlib.date. do they have a new name? Is there a new way to get
automatic date tic location and formating?

dates.AutoDateFormatter  dates.AutoDateLocator

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.

thanks -- I did just find it myself, by looking at the code in axes.plot_dates -- however, the plot_dates docstring is wrong, and they don't seem to be here:

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?

simple snippet (with some additional formatting and stuff you might need):

hence by desire for Auto Formatting.

It does work, but not all that well, though:

thanks. In this case, I'm writing plotting code that I want to work with time series that may span hours, or days, or weeks, or months, ...

In [19]: fig.autofmt_xdate(bottom=0.18) # adjust for correct date labels display

Thanks, this one helps a lot.0

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? But it does work well if you apply it to the figure after my plotting routines. see enclosed for what I'm doing -- this is for plotting wind data and the like, where you have a time series of speeds and directions.
