He also wondered if it was possible to overlay other graphical
elements on a GD::Graph in alignment, and feared it wasn't. I asserted
it was and that I'd don't it, but since we ran out of time, didn't
have time to demonstrate.
The keys are
$graph->set('imagemap'=>'true');
# add data sets ...
my $gd= $graph->make_gd();
### Use of undef for missing values breaks imagemap_dump(),
### if you have nulls may need to cheat.
### my $imagemap_ref =$graph->{'imagemap_data'} ;
my $imagemap_ref = eval { $graph->imagemap_dump() };
if ($imagemap_ref) {... use it ... }
The $imagemap_ref will contain a data structure with x-y's of all the
points. IIRC, it's a ref to an array of arrays, in DataSet major
order. You can then do regular GD graphics on the $gd ... lines,
dots, brushes, ...
