matplotlib-users Mailing List for matplotlib

hello, I'm tinkering with my matplotlibrc file and the changes are not taking effect. specifically I'm changing the hspace and wspace between subplots... although none other options seem to take effect either. I put the matplotlibrc file in my working directory with my script. I also tried making changes to the matplotlirc file in the installation directory, this didn't work either. should pylab be looking in the working directory for matplotlibrc? If so, what might be a reason changes aren't taking effect?
thanks,
Jeff

Look into the arguments of the xticks function. I do things like
tickvals = arange(5.998,6.0025,0.0005);
ticklabs = map(lambda val:"%.4f"%val, tickvals);
ticklabs[0::2] = map(lambda val:"%.3f"%val, tickvals[0::2]);
xticks(tickvals,ticklabs);
to customize.

matplotlib supports mathtext strings, like r'$\Phi_0 = e^{i\pi}$'. Currently, 
if you want to mix mathmode and regular mode, r'for example: $\Phi_0 = 
e^{i\pi}$', you need to enable usetex in your matplotlibrc file. usetex 
requires latex, ghostscript, dvipng to be properly installed, see 
http://www.scipy.org/Cookbook/Matplotlib/UsingTex for more details.

That's a new problem. Eric, it looks like some of your recent changes to 
ticker.py had some unintended side-effects. Do you have time to look into it?

Hi, I'm fairly new to using matplotlib having just stopped using Matlab
and started using Python.

I have two questions about matplotlib.
=20
1) It's pretty easy to include text on a graph, but are LaTex strings
supported? That is, I want to write something like this on my plot:
'\Phi_0 =3D blah...'. When passing a LaTex command as part of text =
string
to be written on a plot in MatLab, it interprets this and displays the
(in this case) Greek symbol. Any suggestions on how this is or should
be done with matplotlib?
=20
2) How do I format how tick mark labels are displayed? I have a plot
whose x-axis runs from 0 to 8.5e-5. But the tick mark labels are
0,0.00001,0.00002,0.00003... This is rather unsightly, but I haven't
found a way to specify the format of these numbers. =20

thanks for any help,
