Method Detail

newUpdate

public AreaGraph2DRendererUpdate newUpdate()

Description copied from class: Graph2DRenderer

Creates a new update for the given graph.

Specified by:

newUpdate in class Graph2DRenderer<AreaGraph2DRendererUpdate>

Returns:

a new update object

update

public void update(AreaGraph2DRendererUpdate update)

Description copied from class: Graph2DRenderer

Applies the update to the renderer.

When sub-classing, one should re-implement this method by first calling it and then applying all the updates specific to the sub-class.

Overrides:

update in class Graph2DRenderer<AreaGraph2DRendererUpdate>

Parameters:

update - the update to apply

draw

public void draw(Graphics2D graphics,
                 Cell1DDataset dataset)

Draws the area to be put behind a graph on the given Graphics2D context, given the Cell1DDataset.

Parameters:

graphics - Graphics2D: can not be null.

dataset - Cell1DDataset

getFocusPixelX

public Integer getFocusPixelX()

getFocusValueIndex

public Integer getFocusValueIndex()
