python.org python installs into /Library/Frameworks/Python.framework
and its main site-packages directory is the line listed above.

That is where *all* packages get installed by default (e.g. by distutils 
or pip).

I suspect the original poster has a conflict with another version of 
python or another package management system such as homebrew. You can 
verify which python is running using "which python" (it should be 
/usr/local/bin/python, which is a symlink to a binary in 
/Library/Frameworks/Python.framework,
or the actual binary itself, depending on your $PATH.

One can test matplotlib using:
python -c "import matplotlib as m ; m.test(verbosity=1)"

If that works then I suspect ipython is misinstalled.

I should have said: 'Consider the _results_ of the following script:'  I originally tried to attach the results I obtained, which showed no change in color for the markers in the legend, while the line connecting the markers in the legend did change color.

Actualy your question is correctly posted but I misread it. Calling
set_color changes only the line color, not the markers. This is
expected and documented behavoir. There are separate methods for the
markers:

line[0].set_markerfacecolor
line[0].set_markeredgecolor

To avoid (not so) rude answer like Mark's one, please try first to refer
to:
- the documentation of the pyplot's commands you use
http://matplotlib.sourceforge.net/api/pyplot_api.html
It tries (pretty well IMHO) to be comprehensive, at least for 99% of use
cases,

- you can set, once for all, the properties of most matplotlib objects
in the configuration file. An example is here:
http://matplotlib.sourceforge.net/users/customizing.html#a-sample-matplotlibrc-file 
It may be a good starting point to determine the name of the property
you are looking for.

Regards,

Actually I had some problems to find the solution on the web.


Finally I've used:   matplotlib.rcParams['legend.fontsize'] = 25.0 and it
works well

Hello Fabien,

There is a font size attribute to ``legend``. Here is the description from
the docstring:

  *fontsize*: [ size in points | 'xx-small' | 'x-small' |
  'small' | 'medium' | 'large' | 'x-large' | 'xx-large' ]
    Set the font size.  May be either a size string, relative to
    the default font size, or an absolute font size in points. This
    argument is only used if prop is not specified.

Cheers,
Nelle

Hello,

The question is in the title :)

Cheers!
Fabien

Hi,

I think I was tired yesterday.
matplotlib.rcParams['xtick.labelsize'] = 20.0 works perfectly also
with xlabel("name", size= 30)

Thanks all,

Fabien

Did you ever find the cause of this?

I found that the get_py2exe_datafiles() method didn't find those fonts but
even when I got the fonts manually I still had the same issue with
matplotlib's Font Manager not being able to find them.

Ben, Goyo,

Thank you for taking the time to consider my question.  I'm sorry that I didn't pose my question correctly.  I should have said: 'Consider the _results_ of the following script:'  I originally tried to attach the results I obtained, which showed no change in color for the markers in the legend, while the line connecting the markers in the legend did change color.

I understand that the lines in the legend are new objects; this is desirable in my case because I have the same symbol with different colors, where the color means one thing (plasma condition), but the symbol means something else (simulated vs measured).  So it makes sense for the markers in the legend describing the meaning of the symbols to be black, as opposed to any of the colors of the markers.   However, setting the legend's new line2d object color properties does not change the appearance of the marker in the legend, only the appearance of the line.  I suspect that this is because the legend marker is drawn separately from the legend line to accommodate the numpoints argument of the legend functions.  Then the question is how to access these markers if they are separate from the line2d objects in the legend.  I didn't even see them in the children of the legend [legend.get_children()].

Thank you for your attention,
Sterling

That is correct.  The lines that one obtains from the get_lines() method of
legend are completely new line objects.  It is only upon the creation of
those lines (at legend creation) that the lines inherit the plot's line
properties.

Now, in the future, it would be nice for artist objects to have shareable
"styles", in which case an edit to a style in one place effects all artists
with the same style object.  But that might be something reserved for
version 2+.

I think it's a design issue, there's no connection kept between plot
lines and the legend. You can change colors in the plot an then call
legend again instead.

Cheers

Goyo

There is imshow(), which will plot an array into the existing axes, as well
as figimage(), which will insert the image into the figure in general.
Each of these function have ways to control placement, particularly
figimage().

Without more information, I can't help much further.

Thanks, that was it. It builds fine afterwards :)

> matplotlib.rcParams['xtick.labelsize'] = 20.0

In your matplotlib config file 
axes.titlesize      : 10      # fontsize of the axes title
axes.labelsize      : 10      # fontsize of the x any y labels
(see http://matplotlib.sourceforge.net/users/customizing.html )

I just create two vectors from a .txt file and I plot them.
I think I have the latest version of matplotlib. I have at least the
last version of python(x,y)


from pylab import*

import matplotlib
matplotlib.rcParams['xtick.labelsize'] = 20.0

B5= genfromtxt("2012-05-14_RC3D3D2C1_D2D1_m18T_18T_Vg32V_20K.dat", usecols =(2))
RH5 = genfromtxt("2012-05-14_RC3D3D2C1_D2D1_m18T_18T_Vg32V_20K.dat",
usecols =(3))
#plot(B5,RH5,"-o",label = "2012-05-14_RC3D3D2C1_D2D1_m18T_18T_Vg32V_20K.dat")


xlabel(u"$ B (T)$", size= 30)
ylabel(u"$R_H (\Omega)$", size= 30)
grid()
legend()
show()

Could you post your code?  What you are describing shouldn't happen.  Also,
which version of matplotlib are you using?

Ben Root

I'm just trying to plot a graph and add a label to each axis of that graph
and change the labelsize of the ticks.

Wait a minute. What exactly are you trying to do?

Thanks,

I've found the problem. I use xlabel("name of my axis", size= 30) after
matplotlib.rcParams['xtick.
labelsize'] = 12.0 and it cancel it! Is it possible to have a name on the
axe and  matplotlib.rcParams['xticks.
labelsize'] = 12.0 ??

Hello,

I want to insert an image in a plot, how can I do?

It's actually 'xtick.labelsize'. No 's'.
