dispose

public void dispose()

register

public void register(Chart chart)

unregister

public void unregister()

initRenderer2d

processSelection

protected abstract void processSelection(Scene scene,
                                         View view,
                                         int width,
                                         int height)

drawSelection

protected abstract void drawSelection(Graphics2D g,
                                      int width,
                                      int height)

Drawing occurs in the selection renderer which as the dimension of the GL2 scene viewport. In other words, one should not expect to draw on the entire canvas if the GL2 scene viewport only covers a slice of the screen. As an example, the following piece of code will draw a border around the GL2 scene: g2d.drawRect(1, 1, chart.getCanvas().getRendererWidth()-2, chart.getCanvas().getRendererHeight()-2);

px - A projected point x value

py - A projected point y value

width - The canvas dimension

height - The canvas dimension

Returns:

true if the point (px,py) is inside the (in,out) mouse selection of a canvas having dimensions (width, height)
