Method Detail

create

public static ScatterChart create(java.util.List<? extends java.awt.geom.Point2D> points,
                                  java.awt.Paint paint,
                                  java.awt.Shape shape)

Create a ScatterChart that is a view on the given list of points. Changes in the given list will be visible in the returned chart.

Parameters:

points - The list of points

paint - The paint for the points. If this is null, then no points will be painted.

shape - The shape for the points. If this is null, then no points will be painted.

Returns:

The ScatterChart

Throws:

java.lang.NullPointerException - If the given list is null

create

public static ScatterChart create(java.util.List<? extends java.lang.Number> xCoordinates,
                                  java.util.List<? extends java.lang.Number> yCoordinates,
                                  java.awt.Paint paint,
                                  java.awt.Shape shape)

Create a ScatterChart that is a view on the given lists of point coordinates. Changes in the given lists will be visible in the returned chart, but care has to be taken that the lists always have the same size.

Parameters:

xCoordinates - The list of x-coordinates

yCoordinates - The list of y-coordinates

paint - The paint for the points. If this is null, then no points will be painted.

shape - The shape for the points. If this is null, then no points will be painted.

Returns:

The ScatterChart

Throws:

java.lang.NullPointerException - If any of the given lists is null

java.lang.IllegalArgumentException - If the given lists have a different size. This can only be checked at creation time.

computeMinX

public static double computeMinX(ScatterChart scatterChart)
