Well, if you think something is wrong, I guess you may have chosen a wrong tool. MPL is mainly for 2d plotting, and not very strong for animation although it supports some. > would it be a good idea to have an array of 1000 points and shift it > left every round to add the new point at the end? Shifting array should be done by numpy, not by matplotlib (I'm not sure if numpy can do this in place). Anyhow, what actually matter is that even if you shift the array, matplotlib will draw all the points in the array every time. One possible option in your case is to save your plot as an image in each round. And at the next round, you plot the newly available data upon the shifted image. http://matplotlib.sourceforge.net/examples/animation/animation_blit_gtk2.html Note that the above example requires svn version of matplotlib.
