Re: [Matplotlib-users] Segmentation fault with EPS output on matplotlib =0.98.5.2
I'm using 'xpdf' now, I think it must be ghostscript acting up. I only need
eps output infrequently so I'll stick with this workaround for the moment.

I cannot reproduce this error.
And I'm not sure if this is a bug in matplotlib or ghostscript.
You may try to use different distiller.
pl.rc('ps', usedistiller=xpdf)
In my machine, both ghostscript and xpdf option works fine.
But my gs version is different than yours
GPL Ghostscript 8.61 (2007-11-21)
If the xpdf option woks, I think it is more likely that this is a bug in
gs.

[Matplotlib-users] Coordinates of contour lines
Hi All, I need to use the coordinates of a contour line for further calculations. Is there a simple way to get the x,y coordinates from a contour object or otherwise? i.e. I have (x,y,z) coordinates and have created a contour map from these. I need the (x,y) coordinates of the contour line with value z0. Cheers Ewald -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

[Matplotlib-users] plotting problem
Hi All, I have a slight problem using matplotlib 0.87.7. I'm using Ubuntu 6.10 and installed mpl from source. I'm running numpy 1.01, also installed from source. If I run the script below, the first plot shows fine. When I close it the second plot should display but it doesn't. I can only get the first plot to show. Thereafter the plot command doesn't seem to work. I tried reinstalling matplotlib. That didn't work. This works fine if I type it into ipython. It also works on my computer running FC5. Any help will be greatly appreciated. -Ewald # Sample script from pylab import * t = arange(10) f = t*t plot(t,f) show() plot(t,f) show() - Take Surveys. Earn Cash.
