HI, I find the very basic animation below has a memory leak (my pagefile usage number keeps growing in the Windows XP Windows Task Manager Performance graph).I don't see this with the "animation_blit_gtk.py" example on:
http://matplotlib.sourceforge.net/examples/index.html (which I used as a starting point for this). In "animation_blit_gtk.py" the set_ydata() routine is used to update the line for the animation and this does not leak. But if you call plot again with the new y_data (instead of using set_ydata), this leaks too. Anyone have an idea on how to stop the leak? thanks, john import gtk, gobject import matplotlib matplotlib.use('GTKAgg') import numpy as np import matplotlib.pyplot as plt from pylab import * from matplotlib.patches import CirclePolygon fig = plt.figure(figsize=(10,6)) ax = fig.add_subplot(111, autoscale_on=False ) canvas = fig.canvas plt.axis([-1, 7, -0.5, 2.2]) def update_line(): global x, y print update_line.cnt if update_line.background is None: update_line.background = canvas.copy_from_bbox(ax.bbox) canvas.restore_region(update_line.background) x_cir = 1.0 + 0.003*update_line.cnt cir = CirclePolygon((x_cir, 1), 0.3, animated=True, \ resolution=12, lw=2 ) ax.add_patch(cir) ax.draw_artist(cir) canvas.blit(ax.bbox) if update_line.direction == 0: update_line.cnt += 1 if update_line.cnt > 500: update_line.direction = 1 else: update_line.cnt -= 1 if update_line.cnt < 100: update_line.direction = 0 return True update_line.cnt = 0 update_line.direction = 0 update_line.background = None def start_anim(event): gobject.idle_add(update_line) canvas.mpl_disconnect(start_anim.cid) start_anim.cid = canvas.mpl_connect('draw_event', start_anim) plt.show() ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
