Hello, I am relatively new to Python, numpy, matplotlib, etc., with a reasonable amount of Matlab experience.
I am trying to do some simple array visualizations before moving on to specific work. e.g. I have a 5x5x10 array and I'd like to see each 5x5 piece as a "frame" with a short pause in between. I realize there are animation methods and such but I think the code below ought to work and don't understand what I'm getting. Expect: A figure window with the first 5x5 piece of the array, a short pause, a new figure window overwriting the old one with the second 5x5 piece, and so on. Equivalent code in Matlab does this. Result: Figure window opens, nothing gets drawn in it, there's a pause, the window closes, and another window opens in the same location with nothing in it, and so on. If I refresh the kernel, create the 3D array, and manually show one slice, it works. As soon as I run the loop, all I get from then on is blank windows whether I do it within a loop or type the matshow, show commands. This happens in iPython with and without the notebook interface. I'm trying to understand Matplotlib in some detail and am watching the SciPy2014 videos along with RTFM. https://www.youtube.com/watch?v=A2adyFMsut0 et.seq. So far, I've come up empty in figuring out what I'm doing wrong. I have Python 2.7.8/Anaconda 2.0.1 Thanks, JBB ===== Test code import numpy as np from matplotlib.pylab import * import time as time # Create a 3D array of "frames" A = np.random.rand(5,5,10) #Turn on interactive mode ion() # Turn off interactive mode # ioff() # Attempt to show each frame with a short delay between frames for k in range(10): matshow(A[:,:,k]) show() time.sleep(1) close() ------------------------------------------------------------------------------ Infragistics Professional Build stunning WinForms apps today!
