[Matplotlib-users] Animation and imshow
I'm trying to figure out how to do animated graphics in pylab using imshow, so I made this little 'hello world' equivalent showing a moving square over two frames. Problem is I have to call draw twice to refresh the image. Anyone can explain why this is so (and how to do this more elegantly)? This is the code: from pylab import * from numpy import * ion() hold(False) frame1 = zeros((200, 200)) frame1[20:40, 20:40] = 255 frame2 = zeros((200, 200)) frame2[20:40, 30:50] = 255 m = imshow(frame1) draw() # shows frame1 m.set_data(frame2) draw() # still shows frame1!!! draw() # and now it shows frame2!?? -- Alex Borghgraef - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
[Matplotlib-users] 3D scatterplot histogram + error ellipses
Hi all, I'm trying to display the histograms of lists of 2D vectors together with their error ellipses in a 3D plot. Plotting the histograms as 3D scatterplots is easy using matplotlib.axes3d.Axes3D( ).scatter3D( x, y, h ), but how do I draw the error ellipse in the ( x, y ) plane. I know how to create a matplotlib.patches.Ellipse object, but I'm pretty clueless on how to integrate it into the figure. Any help? -- Alex Borghgraef - This SF.net email is sponsored by: Splunk Inc.
