Suppose we have data of this form:

1  2  5  4
3  6 15 12
6 12 30 24
9 18 45 36

We want a plot containing:
the second column against the first
the third  column against the first
the fourth column against the first

This directory shows how to use a script to convert the data into a
form that the xyplo program can then plot.
