    • Method Detail

      • getColor

        public int getColor()
        Suggested color number.
        Returns:
        Color number

      • add

        public void add​(double x,
                double y)
        Add a coordinate pair, but don't simplify
        Parameters:
        x - X coordinate
        y - Y coordinate

      • getX

        public double getX​(int off)
        Curve X value at given position
        Parameters:
        off - Offset
        Returns:
        X value

      • getY

        public double getY​(int off)
        Curve Y value at given position
        Parameters:
        off - Offset
        Returns:
        Y value

      • size

        public int size()
        Size of curve.
        Returns:
        curve length

      • iterator

        public XYPlot.Curve.Itr iterator()
        Get an iterator for the curve. Note: this is not a Java style iterator, since the only way to get positions is using "next" in Java style. Here, we can have two getters for current values! Instead, use this style of iteration: 
         
 for (XYCurve.Itr it = curve.iterator(); it.valid(); it.advance()) {
   doSomethingWith(it.getX(), it.getY());
 }
        Returns:
        Iterator
