You're already using "ax.legend", what kind of OO way do you want?
Instead of calling plt.legend, you may do ax.legend([s],[str(i)]) Or, if you know what you're doing, you can do leg = ax.legend([s],[''], loc=0) and in the for loop, leg.texts[0].set_text(str(i)) Regards, -JJ On Thu, Feb 11, 2010 at 5:56 AM, Jorge Scandaliaris <jorgesmbox...@yahoo.es> wrote: > Hi, > I am re-using a scatter plot in the same figure for interactively displaying > results without ending up with 30 windows open.
