plot 'airy.txt' using 1:2 with lines linewidth 4, \
     'airy.txt' using 1:3 with lines linewidth 4

The file 'airy.txt' contains the values of the Airy functions, and can be produced by the following Octave commands.

xs = linspace(-15, 5, 1000);
tbl = [ xs; airy(0,xs); airy(2,xs) ];
tbl = tbl';
save -ascii airy.txt tbl;
