[Matplotlib-users] Setting tick labelsize programatically

[Joshua J. K. <jo...@ee...>]

[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.

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. :)

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? :)

Thanks!

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!
