afaik it doesn't look like there's anything missing if anything there is some superfluous code: fig1 = plt.figure(1) ax1 = fig1.gca() and the animated=True kwarg I don't what is optimum, matplotlib has always been a bit hackish for animation i think best Michael Nandris > > > Alan Isaac > > PS The following almost works (i.e., works, > but then exits with an error). > > import matplotlib.pyplot as plt > from time import sleep > from numpy import zeros > > plt.ion() > plt.hold(False) > > data = list() > slices = list() > for i in range(5): > frame = zeros( (200,200) ) > frame[20:40,10*i:10*i+20] = 255 > data.append(frame) > > fig1 = plt.figure(1) > ax1 = fig1.gca() > for frame in data: > plt.imshow(frame, axes=ax1, animated=True) > sleep(0.2) -- "When you think of the long and gloomy history of man, you will find far more hideous crimes have been committed in the name of obedience than have been committed in the name of rebellion".
