Hi, =20 I 'm writing a python program that draws figures one by one interactively with the user's input in dos mode. Basically, I give the program a decision after each figure and then it draws the next one. After the first figure, it got very much slowed down for the second one and crashed for the third one. I feel like it has some memory issues as I keep using 'show' after I close each. I used 'clf()' before I draw a new one, but it doesn't seem to help. Any idea? Thanks. =20 Young Jin
This might help you it destroys the whole window: pylab.get_current_fig_manager().destroy() and then you open it again with show Lee, Young-Jin wrote: > > Hi, > > I ’m writing a python program that draws figures one by one > interactively with the user’s input in dos mode.

Thanks much! But, it didn't help. The second figure got still really slow and closes right away after it finishes drawing not giving enough time to me to see the figure. Then, it crashed for the third one. Any idea?

Folks, I need your help. I'll explain a little further what happens. Following is a test program,'test.py', and screen shot of the error message. Here, 'test.py' is simple chart of sinusoidal function in http://matplotlib.sourceforge.net/screenshots.html (simple_plot.py), but have two of them in series. I tried Wolfgang's suggestion but it doesn't help. Any idea? Test.py: from pylab import * t =3D arange(0.0, 2.0, 0.01) s =3D sin(2*pi*t) plot(t, s, linewidth=3D1.0) xlabel('time (s)') ylabel('voltage (mV)') title('About as simple as it gets, folks') grid(True) show() clf() t =3D arange(0.0, 2.0, 0.01) s =3D sin(2*pi*t) plot(t, s, linewidth=3D1.0) xlabel('time (s)') ylabel('voltage (mV)') title('About as simple as it gets, folks') grid(True) show() Execution of test.py: c:\Python24>python test.py c:\Python24\lib\site-packages\matplotlib\numerix\__init__.py:53: DeprecationWarn ing: numarray use as a numerix backed for matplotlib is deprecated DeprecationWarning, stacklevel=3D1) Fatal Python error: PyEval_RestoreThread: NULL tstate This application has requested the Runtime to terminate it in an unusual way.

Comment out the first one, and replace the "clf()" with "figure()" and all is well. Or, use "draw()".
