Suggested color (number).

Constructor Detail

XYPlot.Curve

public XYPlot.Curve(int color)

Constructor.

Parameters:

color - Color number (curve number)

XYPlot.Curve

public XYPlot.Curve(int color,
            int size)

Constructor.

Parameters:

color - Color number (curve number)

size - Expected size

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
