Interface IFunctionLine

All Superinterfaces:

java.lang.Cloneable, IDataLine, IReferenceObj

public interface IFunctionLine
extends IDataLine

This class is used to draw function lines y = f(x) in a 2D scatter chart You may call newFunctionLine(...) of IDataLineSet interface to get a new object Note: (1) This class is only useful for 2D scatter charts. (2) The function cannot be saved to or read from a cht/tpl file (3) No line style supported For instance, QbChart chart = new QbChart(...); IFunctionLine line = chart.gethDataLineSet().newFunctionLine(...);
