ax.plot always returns a list because it may plot more than one line. The choice of syntax for the caller of the function is just for convenience. One could just as easily do: lines = ax.plot(t, y1, lw=2, color='red', label='1 hz') line = lines[0] Cheers, Mike -- Michael Droettboom Science Software Branch Operations and Engineering Division Space Telescope Science Institute Operated by AURA for NASA ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
