[Kmatplot-general] how to plot a batch of xy curves at an easy rate?

[<zho...@gm...>]

everyone,
 Does anyone knows how to plot a great number of curve in one figure? I
think it's not a good idea  to use Graph\wizard to plot them one by one,
because i have more than 100 lines to plot. could somebody give me a piece
of advice? Thanks in advance.
