Class CalcGraphSet

com.numobjects.mathbeans.CalcGraphSet

public class CalcGraphSet

implements java.io.Serializable

Calc set with graphing capabilities. Contains a calc set with the plotter. The component provides the possibility to choose the independent variable, its range and which of the dependencies to plot. The chosen functions are then plotted together. The graph may be detached and resized as desired. Graphs can be printed. Expressions corresponding to the functions are set by the same rules as for the CalcSet.
