Hey Alex, I always just figure this out on my own. There might exist a more elegant way though. Starting with this: import matplotlib.pyplot as plt fig = plt.figure() ax1 = fig.add_subplot(111) ax2 = ax1.twinx() # plot stuff # So then you could do something like: ytx1 = ax1.get_yticks() ...and then use to len(ytx1) and range() to ax2.set_yticks(blahblah). The tricky part is picking a max for your range() so that your stepsize produces nice numbers. > Also, on a somewhat related note, is there a simple way to force the y > ticks > to start at 0 rather than some other value? ax1.set_ylim(ymin=0) HTH, -paul h. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
