The call to legend needs a list of handles (artists) and a list of labels. If using the line JDH suggested, try date_axes.legend((morning_plot[0], evening_plot[0], value_plot[0]), ("Morning", "Evening", "Value"), numpoints=1, loc=0, borderpad=1, shadow=True, fancybox=True) With the code as it is try date_axes.legend((morning_plot[0], evening_plot[0], value_plot[0][0]), ("Morning", "Evening", "Value"), numpoints=1, loc=0, borderpad=1, shadow=True, fancybox=True) If neither works, then you might need to provide more information. -Sterling ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
