Method Details

getSeriesLegendRenderGraphicHeight

protected abstract double getSeriesLegendRenderGraphicHeight(S series)

doPaint

protected abstract void doPaint(Graphics2D g)

paint

public void paint(Graphics2D g)

Specified by:

paint in interface ChartPart

getBoundsHintVertical

private Rectangle2D getBoundsHintVertical()

determine the width and height of the chart legend

getBoundsHintHorizontal

private Rectangle2D getBoundsHintHorizontal()

determine the width and height of the chart legend with horizontal layout

getSeriesTextBounds

Map<String, Rectangle2D> getSeriesTextBounds(S series)

Normally each legend entry just has one line of text, but it can be made multi-line by adding "\\n". This method returns a Map for each single legend entry, which is normally just a Map with one single entry.

Parameters:

series -

Returns:

getLegendEntryHeight

float getLegendEntryHeight(Map<String, Rectangle2D> seriesTextBounds,
 int markerSize)

getLegendEntryWidth

float getLegendEntryWidth(Map<String, Rectangle2D> seriesTextBounds,
 int markerSize)

paintSeriesText

void paintSeriesText(Graphics2D g,
 Map<String, Rectangle2D> seriesTextBounds,
 int markerSize,
 double x,
 double starty)

getBounds

public Rectangle2D getBounds()

Specified by:

getBounds in interface ChartPart
