[Matplotlib-users] Legend Font Size

[Alex R. <ale...@gm...>]

Hi,

I'm new to pylab, and I find it very usefull. I want to know how is 
possibile to change font properties in legend (I particular fontsize): I 
tried adding "prop = FontProperties("smaller")" in legend(), but this 
give me an error... maybe I'm wrong...

Thanks, Alex.

Try:

  prop = FontProperties( size="smaller" )


 From font_manager.py:

   size    - Either an absolute value of xx-small, x-small, small,
             medium, large, x-large, xx-large; or a relative value
             of smaller or larger; or an absolute font size, e.g. 12;
             or scalable.

[Matplotlib-users] Legend with multiple histograms

[kristen k. <co...@ya...>]

Hi everyone
Does anyone know how to asign different patches in
legend when plotting 2 or more histograms in the same
figure.
I've tried:
legend((patches1,patches2),(hist1,hist2)) ,

but this gives the same patches in the legend inset.

Kristen

I'm assuming patches1 and patches2 are the return values from hist, in
which case they are each a *list* of patches.  What you want to do is
pass a *single* item from each of those lists as representative
patches.

  legend( (patches1[0],patches2[0]), ('label1', 'label2') ) 

Next time if you post a more complete code snippet, I won't have to
guess what patches1 and patches2 are!

Hope this helps,

[Matplotlib-users] Changing fontsize in legend

[kristen k. <co...@ya...>]

Hi again
Working with legend I've encountered another problem.
Changing the fontsize in a legend seems to be a little
harder than first assumed. Is there an easy way to do
this??

 From the mailing list a couple of days ago...

You need to pass in a FontProperties instance that specifies the size you want:

prop = FontProperties(size="x-small')

size    - Either an absolute value of xx-small, x-small, small,
           medium, large, x-large, xx-large; or a relative value
           of smaller or larger; or an absolute font size, e.g. 12;
           or scalable

i.e. lgnd = ax.legend((lines, labels, prop = FontProperties(size="x-small'), 
..other_params_as_required)

PS This looks like something to add to my 'Getting Started' document....

http://matplotlib.sf.net/examples/legend_demo.py shows you how to
customize the legend text font size.  The examples directory is really
an indispensable tool in learning matplotlib.  If you are using the
source distribution, the examples directory is included.  If you are
using a binary distribution, a zip file is found here
http://matplotlib.sourceforge.net/matplotlib_examples_0.72.zip

The relevant code fragment from legend_demo.py is

  ltext  = leg.get_texts()      # all the text.Text instance in the legend
  set(ltext, fontsize='small')  # the legend text fontsize
