Text labels on plot axis?

Dear all

is there a way to put text labels on a plot axis instead of numbers?

A little background: I've got some data on different chemical elements,
and I want to compare the data in a plot. I'd like to use the x-axis for
the different elements (with the element names as labels on the x-axis)
and the values on the y-axis.

For instance:

el = [ H ; Be ; C ; Ca ]; % element names
x  = [ 1 ; 2 ; 3 ; 4 ]; % dummy x-coordinates
y  = [0.1 ; 0.2 ; 0.15 ; 0.22]; % y-coordinats, values

plot(x,y); % this will give 1, 2, 3, and 4 on the x axis.

--> replace 1, 2 , 3, and 4 with the element names in el?

I'm pretty sure this can be done with gnuplot, so it should be possible to
do it from within Octave using gset or __gnuplot_raw__ (although these
commands will not be supported in the future). Any suggestions?
