Kurt: If you want the Lambert conformal projection, you should use
projection='lcc', not 'ortho'.
Nevertheless, your example works for me if I change the order of the
arguments passed to the Basemap instance to
x, y = m1(COSLon,COSLat)
x, y = m1(WASHLon,WASHLat)
Note, longitude goes first.
Also, if you want 'full resolution' coastlines, use resolution='h'.

[Matplotlib-users] Setting font family in ticks not possible. Bug?
Dear Mailinglist,
Today I tried to change the fontset to sans-serif for a whole plot.
Everything except the ticks could be adjusted.
This is what I tried first:
***
ffont = {'size':'20','family':'sans-serif'}
xticks(**ffont)
***
No change in the font family. But I can change the size without
problems. I removed the ~/.matplotlib/FONTCACHE stuff as described
here(2).
Following (1) I tried again to change the font using
***
import pylab
pylab.figure()
ax = pylab.axes()
ax.plot(pylab.arange(10))
xlabels = ax.get_xticklabels()
xlabel0 = xlabels[0] # one of the xtick
labels
xlabel0.get_fontsize()
xlabel0.set_fontsize(20)
pylab.show()
***
Again nothing changed.
Using ipython I got this:
***
In [192]: xlabels[0].get_fontname()
Out[192]: 'Bitstream Vera Serif, New Century Schoolbook, serif'
In [195]: xlabels[0].set_family(sans-serif)
In [196]: xlabels[0].get_fontname()
Out[196]: 'Bitstream Vera Sans, Lucida Grande, Verdana, sans-serif'
In [197]: show()
***
Summary:
It appears to me like I can change the default fontfamily, but somehow
there is no change in the output.
What could be the problem?
Best regards:

Hmmm... This works for me. What backend are you using? Perhaps it
isn't updating? Also, do these two lines + show() alone not work, or is
it only in the context of something else?
Also, what platform are you on?

Re: [Matplotlib-users] [wxpython-users] Controlling the wxpython matplotlib-frame
Have you tryied : ipython -pylab ? It launch an ipython shell that support mathplotlib gui loop. -Message d'origine- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] ] De la part de Wolfgang Kerzendorf Envoyé : mercredi 26 mars 2008 08:31 À : matplotlib-users@lists.sourceforge.net; [EMAIL PROTECTED] Objet : [wxpython-users] Controlling the wxpython matplotlib-frame Hello all, I have trouble with one of my scripts that uses matplotlib when using python or ipython. The first time it opens, it does not hand the control back o the shell and can be used to work on the matplotlib figure interactively (I use an event handler and picker objects to change my plots) so it works really well. After I close the window the control is given back to the shell. This is how I want it to work, however at the second time the matplotlib plot opens the shell does not stop anymore, the script continues. When I used GTKAgg on my old linux box I had the same issue and bound a key to pylab.get_current_figure_manager().destroy(), which looked like a hack to me but worked. This does not work anymore with wxPython, because the next time I open a plot I get an exception: PyDeadObjectError: The C++ part of the FigureFrameWxAgg object has been deleted, attribute access no longer allowed. I also think destroying the figure_manager is not the right way to do that. Whats a goog solution for this? Thanks in advance Wolfgang P.S.: I know I posted a similar thing yesterday, but I thought rephrasing the question might help with finding the solution ___ wxpython-users mailing list [EMAIL PROTECTED] http://lists.wxwidgets.org/mailman/listinfo/wxpython-users - Check out the new SourceForge.net Marketplace.

I guess you could read the rcParams value that corresponds to the screen display and set rcParams['savefig.dpi'] to that value (this might work): mydpi = rcParams['figure.dpi'] rcParams['savefig.dpi'] = mydpi But that seems slightly hackish and maybe not much more elegant than what you are currently doing with passing dpi into savefig.

[Matplotlib-users] Zero length quiver/savefig bug
Quiver doesn't seem to be able to handle begin passed zeros for the vector lengths. The full error output is below. I'm running Leopard with macpython 2.5.2 using matplotlib-0.91.2-py2.5-macosx-10.3-i386.egg The following code does not work: rx = numpy.array([0.0,0.0]) ry = numpy.array([1.0,-1.0]) ax = numpy.array([0.0,0.0]) ay = numpy.array([0.0,0.0]) quiver(rx,ry,ax,ay) savefig(image2.png,format='png') The same code works if any of ax or ay are nonzero.

[Matplotlib-users] scipy, matplotlib import errors
Hello, could someone please help me understand a strange problem, possibly
associated with PYTHONPATH. When I import matplotlib, pylab, or scipy from
any directory other than the root installation directory, it fails. However,
if I'm in the python installation directory there are no errors. Thanks in
advance! Please see below:
