DESCRIPTION

The GD.Graph.linespoints plugin provides an interface to the GD::Graph::linespoints class defined by the GD::Graph module. It allows one or more (x,y) data sets to be plotted as y versus x lines, plus symbols placed at each point, in addition to axes and legends.

See GD::Graph for more details.
