hello, > why is it actually not possible to do something like the following piece > of code? > ioff() > plot commands > draw() > ion() actually, i did some test now (modification of the example http://www.scipy.org/Cookbook/Matplotlib/Animations site):
from pylab import * ioff() x = arange(0,2*pi,0.01) # x-array line, = plot(x,sin(x)) draw() displays nothing, then ion() for i in arange(1,200): line.set_ydata(sin(x+i/10.0)) # update the data draw() # redraw the canvas displays nothing as well, but shows the same 'lag' as when running the whole code in interactive mode. that means that the data is processed, the graphics is plotted, just the window is not displayed. i thought that ioff() is present exactly for this purpose. unfortunately, the documentation page http://matplotlib.sourceforge.net/interactive.html shows only an example where an image file is produced first with ioff(), the figure is closed and something is then displayed with ion(). when i later issue another plot() command (i.e., plot(random(20), random(20)), it is displayed and shows also the last part of the sin(x) plot... the thing i want to achieve is maybe impossible - i'd just love to know why, or what am i doing wrong... i'm very grateful for any hints. best, lubos -- Lubos [EMAIL PROTECTED]" http://www.lubos.vrbka.net ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
