in reply to Adding symbols to GD::Graph ??

In continuing a theme of talking to myself...

It looks like the GD::Graph has a few experimental methods that might do what is desired here:
$graph->get_hotspot($dataset, $point) Experimental: Return a coordinate specification for a point in a datas +et. Returns a list. If the point is not specified, returns a list of +array references for all points in the dataset. If the dataset is als +o not specified, returns a list of array references for each data set +. See "HOTSPOTS". $graph->get_feature_coordinates($feature_name) Experimental: Return a coordinate specification for a certain feature +in the chart. Currently, features that are defined are axes, the coor +dinates of the rectangle within the axes; x_label, y1_label and y2_la +bel, the labels printed along the axes, with y_label provided as an a +lias for y1_label; and title which is the title text box. See "HOTSPO +TS".

Perhaps with that I can then get coordinates with which to pass to the polygon and then apply to the image.
