Constructor Detail

MultiAxisLineGraph2DRenderer

public MultiAxisLineGraph2DRenderer(int imageWidth,
                                    int imageHeight)

Creates a new line graph renderer.

Parameters:

imageWidth - the graph width

imageHeight - the graph height

Method Detail

newUpdate

public MultiAxisLineGraph2DRendererUpdate newUpdate()

Description copied from class: Graph2DRenderer

Creates a new update for the given graph.

Specified by:

newUpdate in class Graph2DRenderer<MultiAxisLineGraph2DRendererUpdate>

Returns:

a new update object

getInterpolation

public InterpolationScheme getInterpolation()

The current interpolation used for the line.

Returns:

the current interpolation

update

public void update(MultiAxisLineGraph2DRendererUpdate 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<MultiAxisLineGraph2DRendererUpdate>

Parameters:

update - the update to apply

draw

public void draw(Graphics2D g,
                 List<Point2DDataset> data)

Draws the graph on the given graphics context.

Parameters:

g - the graphics on which to display the data

data - the data to display

calculateRanges

protected void calculateRanges(List<Range> xDataRange,
                               List<Range> yDataRange,
                               int length)

calculateLabels

protected void calculateLabels()

Description copied from class: Graph2DRenderer

Calculates:

• The font for the labels
• The margins based on labels

Overrides:

calculateLabels in class Graph2DRenderer<MultiAxisLineGraph2DRendererUpdate>

calculateGraphArea

protected void calculateGraphArea()

Description copied from class: Graph2DRenderer

Calculates the graph area based on:

• The image size
• The plot ranges
• The value scales
• The font for the labels
