matplotlib-devel Mailing List for matplotlib

Sounds good to me.  I guess when this is done I need an example rc
file and a little info on how it should work.

This is what I am trying to accomplish, using the existing scaling framework. 
Rather than "main + or - X", it multiplies main by one of the following:

{'xx-small': 0.579, 'x-small': 0.694, 'small': 0.833,
                 'medium': 1.0, 'large': 1.200, 'x-large': 1.440,
                 'xx-large': 1.728}

Ok. So currently a user can put font.size:23.0, or font.size:medium or even 
"large". The latter makes things very confusing, because who knows what the 
reference point is? (Its 12, but its not clear.)

I propose the following change: font.defaultsize demands a point size, and 
then allow the relative font sizes to scale that size. Also, add a 
text.fontsize rc parameter to allow such scaling for text (this is what 
font.size does now, I think). 

Are these changes ok, or should I just leave everything alone?

If you want to use rc defaults for kwargs, you do not want to use them
in the function definition, because then they will be set a module
load time and the defaults cannot be changed dynamically.  Rather, you
want to use this idiom (eg lines.py)


    def __init__(self, xdata, ydata,
                 linewidth       = None, # all Nones default to rc
                 ...):
        if linewidth is None   : linewidth=rcParams['lines.linewidth']

Then if the user changes the rc param value, the constructor default
changes too.

I just want to double check before I commit this. We offer a font.size rc 
setting, and users can modify that size by setting fontsize='medium' or 
'large', etc. However, font.size does not globally set the default font size, 
to axis labels, ticklabels, etc, they remain 12pt as default. Should this be 
changed? If so, the change is simple:
from this:
    def __init__(self, size=12.0, weight='normal'):
to this:
    def __init__(self, size=rcParams['font.size'], weight='normal'):
