Setting tick labelsize programatically

Community matplotlib-users
#1

[Trying one more time.]

I've read docs, search the list archive, and tried to step through code.

How can I set things like xtick.labelsize and ytick.labelsize via the
object oriented interface? I have a graph object, and I can't find
anywhere in the data structure for the completed graph where the tick
label sizes are stored, nor can I find functions to set them.

Even with lots of stepping through code, I can't find where I would
manually set the size of the ticks.

I know about matplotlib.rc, and the setting in the config file, but I
don't want to set things globally, I want to set per graph.

Thanks for any pointers!

The docs you are looking for are
http://matplotlib.sourceforge.net/users/artists.html.

anywhere in the data structure for the completed graph where the tick
label sizes are stored, nor can I find functions to set them.

Here is one way to do it::

    for label in ax.get_xticklabels() + ax.get_yticklabels():
       label.set_fontsize(12)

But the artist tutorial above will give you a more in-depth
explanation of the various containers and methods.

Sigh...how simple. Thank you very much!

OK, so it's half working. :slight_smile:

I have code such as this:

    for label in self.main_axes.get_xticklabels():
        tick.label.set_fontsize(self.xtick_labelsize)

    main_ticks = self.main_axes.get_yticklabels()
    sub_ticks = (self.sub_axes.get_yticklabels()
                 if hasattr(self.sub_axes, 'get_yticklabels') else [])
    for label in main_ticks + sub_ticks:
        label.set_fontsize(self.ytick_labelsize)

'self' is an object that gets turned in to a plot on a figure.
the sub_axes are because we have centigrade on one end of the plot, and
Fahrenheit on the other end. The yticklabel code works fine. The
xticklabel code has no effect.

The X axis is an AutoDateLocator and apparently set_fontsize isn't
having an effect with that. I tried setting the font size even after
setting the locator, and that doesn't appear to have any effect. Can
you point me to the relevant docs on the subject? :slight_smile:

Thanks!

        tick.label.set_fontsize(self.xtick_labelsize)

Perhaps the line above should be

    label.set_fontsize(self.xtick_labelsize)

instead.

Well, yes, it should, and I apparently caught that bug AFTER I sent the
e-mail, but alas it was left over from messing around with the code.
The code is now correct:

for label in self.main_axes.get_xticklabels():
    label.set_fontsize(self.xtick_labelsize)

But still does not affect the x date labels. Thanks for the pointer,
though!
