Re: [Matplotlib-users] pylab crashes python
Are you running the script again or plotting a second time in the same script? You might need to set matplotlib to plot interactively. See the documentaion about interactive plotting. You need to set the back end graphics to the right kind for interactive plotting. E.g. in .matplotlibrc backend : TKAgg # should work for interactive interactive : True # see http://matplotlib.sourceforge.net/interactive.html -- Lou Pecora My views are my own. 8:00? 8:25? 8:40?

I'm not sure pylab supports this use. I think once you close the plot window, you have shut down the wx.App, then when you plot again, it tries to create it again, but you can't start and stop wx.Apps over again in the same process. I think you can do what you want by using ipython, so that you don't have to close the figure window to get your prompt back. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] - Take Surveys.

[Matplotlib-users] dvipng version error running matplotlib on windows
I am getting a dvipng version error when I run:
import Numeric,matplotlib
matplotlib.use('Agg')
from matplotlib import rc
rc('text', usetex=True)
import pylab
pylab.figure(num=1,figsize=(6,4))
pylab.plot(Numeric.arange(10), Numeric.arange(10)**2)
pylab.axis( (0,9,0,81) )
pylab.xlabel(r'$width$')
pylab.ylabel(r'$Height (km)$')
filename='c:/test.png'
pylab.savefig(filename,dpi=100)
pylab.clf()
here is a bit of the error message:
File "C:\Python24\Lib\site-packages\matplotlib\texmanager.py", line 58, in
get_dvipng_version
raise RuntimeError('Could not obtain dvipng version')
RuntimeError: Could not obtain dvipng version
I have winXP, python2.4, matplotlib0.87, miktex2.5. I downloaded dvipng1.9
from sourceforge, but have no idea what to do with it. do i need a 'c'
compiler to install it?

[Matplotlib-users] pylab crashes python
hi, I use python 2.4, matplotlib and WXpython on OS X. I plot and show something and every thing works fine (the plot is shown in the python.app). I close the plot window. I plot another thing. It is shown again with python.app, but now python.app crashes... every second plot causes a crash in python.app... has anybody a hint? thanks Jan - Take Surveys. Earn Cash.

I searched the forum for something similar and could not find anything.
Also my latex can typeset the above if i run it in a separate tex file. I
am using the GTKAgg backend.
Could someone please help me out?

Hello, i have made bar charts but I was wondering if there is a way to show on top of each bar the real content/counts, like a label; I generate static plots so the dynamic showing of the counts on focusing on the bar does not help me.

See http://www.scipy.org/Cookbook/Matplotlib/UsingTex for information about
package requirements and configuration. If you can't get dvipng through
MikTeX, and the sourceforge page doesnt distribute a windows executable, then
you will have to compile it.

Re: [Matplotlib-users] pylab crashes python
I found an example script I got to work for WX. I guessed that the ws.app had to be deleted to plot again. Here it is (the part that runs the code and creates the WX.app: if __name__ == '__main__': app = wx.PySimpleApp(0) frame = PlotFigure() frame.plot_data() frame.Show() app.MainLoop() #must delete app before reusing for wxPython del app# << THE CRUCIAL STEP print "done with plot 1" app = wx.PySimpleApp(0) frame = PlotFigure() frame.plot_data() frame.Show() app.MainLoop() print "done with plot 2" Without the delete you get a crash/hang. -- Lou Pecora My views are my own.
