I would like to plot multiple graphs in a single plot
frame. Something like this:

plot(X, Y1, type='l', col='red')
lines(X, Y2, col='green')
lines(X, Y3, col='blue')

etc. The problem with this approach is, however, that
the range of the y-axis will be set according to the
minimum and maximum values of Y1 only. I would like to
generate a plot that shows all the values of Y1, Y2,
and Y3, no matter what their ranges are.

Is there an easy way to do this?
