Try using values_format, formatting the maxima as numbers and everything else as an empty string, e.g.
sub v_format {
my $value = shift;
if ($value >= ($MAX - $EPSILON)) {
return $value
} else {
return '';
}
$my_graph->set('values_format' => \&v_format);

If I'm reading your post correctly, take a look at these values in the docs for GD::Graph
x_label_skip, y_label_skip
Print every x_label_skipth number under the tick on the
x axis, and every y_label_skipth number next to the tick
on the y axis. Default: 1 for both.
Update:
I misread this question, but the settings I pointed out above are still useful for some graphing ops, so I'll leave the post intact.

ryddler,
Thanks for your post. Yeah, what I'm looking to do is label certain points on the graph (like the maximum Y values). I've got the tic labeling figured out.
While I'm on this topic...are there any monk recommendations for another graphing module that do a better job at what I'm trying to do? Basically, I'm taking spectra which contain thousands of x, y data points and I just want to do some automated labeling of some of the biggest peaks. Thanks...
