It is designed to be used in conjunction with the Graph2D class and DataSet class for plotting 2D graphs.To work with the other classes a system of registration is used.The axes have to be attached to the controlling Graph2D classand the DataSet's have to be attached to both the Graph2D classand the Axis class.This way the 3 main classes Graph2D, Axis and DataSet know of eachothers existence.This does not mean the classes cannot be used independently, they canbut in this mode nothing is automated, the user must code everythingmanually<dl> <dt> <b>Version:</b> <dd> 1.12, 1996/09/12 03:27:07.
