Constructor Detail

LineTimeGraph2DRenderer

public LineTimeGraph2DRenderer(int imageWidth,
                       int imageHeight)

Creates a new line graph renderer.

Parameters:

imageWidth - the graph width

imageHeight - the graph height

Method Detail

newUpdate

public LineTimeGraph2DRendererUpdate newUpdate()

Description copied from class: TemporalGraph2DRenderer

Creates a new update for the given graph.

Specified by:

newUpdate in class TemporalGraph2DRenderer<LineTimeGraph2DRendererUpdate>

Returns:

a new update object

getInterpolation

public InterpolationScheme getInterpolation()

The current interpolation used for the line.

Returns:

the current interpolation

update

public void update(LineTimeGraph2DRendererUpdate update)

Description copied from class: TemporalGraph2DRenderer

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 TemporalGraph2DRenderer<LineTimeGraph2DRendererUpdate>

Parameters:

update - the update to apply

draw

public void draw(Graphics2D g,
        TimeSeriesDataset data)

Draws the graph on the given graphics context.

Parameters:

g - the graphics on which to display the data

data - the data to display
