If you set "_nolegend_" as label, that line will not be displayed in the legend. http://matplotlib.sourceforge.net/api/pyplot_api.html?highlight=legend#matplotlib.pyplot.legend Or, you may manually select which lines to be displayed. See the above documentation for more details. > finally, how can i make it so the legend does not interfere with the plot? > right now the lines appear "behind" the legend. it'd be great if the legend > could be made to be in the background of the line (i.e. be transparent.) > reduce the zorder of the legend less than that of the lines. http://matplotlib.sourceforge.net/api/artist_api.html?highlight=zorder#matplotlib.artist.Artist.set_zorder e.g., l = legend() l.set_zorder(0) Regards, -JJ > thank you. > > ------------------------------------------------------------------------------ > Enter the BlackBerry Developer Challenge > This is your chance to win up to $100,000 in prizes!
