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.
