Blitting will improve the performance when significant portion of your plot is (semi-)stationary. And I guess your example, as it is, may not benefit from blitting. A. init 1. draw stationary artists (animated=False) on the canvas 2. save the area of canvas as a pixmap array. B. looping for animation 1. restore the stationary artists by blitting the saved pixmap array 2. draw animated artists. 3. optionally update the saved pixmap. And your speed gain comes from B.1 Regards, -JJ ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
