org.jdesktop.swingx.JXGraph

A plot represents a mathematical transformation used by {@link JXGraph}. When a plot belongs to a graph, the graph component asks for the transformation of a value along the X axis. The resulting value defines the Y coordinates at which the graph must draw a spot of color.

Here is a sample implementation of this class that draws a straight line once added to a graph (it follows the well-known equation y=a.x+b):

 class LinePlot extends JXGraph.Plot { public double compute(double value) { return 2.0 * value + 1.0; } }

When a plot is added to an instance of JXGraph, the JXGraph automatically becomes a new property change listener of the plot. If property change events are fired, the graph will be updated accordingly.

More information about plots usage can be found in {@link JXGraph} inthe section entitled Plots.

        controlPanel.add(label);
        add(controlPanel, BorderLayout.NORTH);


        Point2D origin = new Point2D.Double(0.0d, 0.0d);
        Rectangle2D view = new Rectangle2D.Double(-10.0d, -10.0d, 20.0d, 20.0d);
        JXGraph graph = new JXGraph(origin, view, 5, 5, 5, 5);
        plot = new SimpleLinePlot();
        graph.addPlots(Color.RED, plot);
        add(graph);
    }
