DESCRIPTION

75       The GD.Graph.bars plugin provides an interface to the GD::Graph::bars
76       class defined by the GD::Graph module. It allows one or more (x,y) data
77       sets to be plotted with each point represented by a bar, in addition to
78       axes and legends.
79
80       See GD::Graph for more details.
