How to Plot the Third Column Versus the First in Maple 9.5?

[Acili]

I have a data file with 3 columns, and I am running Maple version 9.5

I want to read and plot the third column versus the first. How?

When I do:

:> datafile=readdata(datafile, float, 3);
and then

:>plot(datafile);

Maple just gives me a plot of column 2 versus 1 - leaving the 3rd. column.

Help me.
