Question: Syntax for plotting 2 sets of data on one plot

Hi:

I have three lists: [x],[y1] and [y2] and want to plot y1 and y2 against x.

The command

pointplot(x,y1) gives me what I want for y1 and

pointplot(x,y2) gives me what I want for y2, BUT

I can't figure out a way to put y1 and y2 on the SAME plot against x instead of two separate plots.

There must be a way... any suggestions?

Thanks.
