Constructor Detail

Pie3DRenderer

public Pie3DRenderer()

Method Detail

getThicknessRatio

public float getThicknessRatio()

Returns the thickness of the pie chart as a ratio of the pie diameter

Returns:

the thickness of the pie chart as a ratio of the pie diameter

setThicknessRatio

public void setThicknessRatio(float thicknessRatio)

Specify the thickness of the pie chart as a ratio of the pie diameter. By default, this has a value of 0.2

Parameters:

thicknessRatio - the thickness of the pie chart as a ratio of the pie diameter

getSpotlightRatios

public float[] getSpotlightRatios()

Get the three spotlight ratio values

Returns:

an array of 4 floats used for the spotlight colour ratio values

setSpotlightRatios

public void setSpotlightRatios(float[] ratios)

Set four brightness ratios used to apply to colours on the main surface of the pie chart to give a spotlight effect. A ratio of 0.5 leaves the input color unchanged, larger values make the color brighter and smaller values make the color dimmer. The default value is {0.48f, 0.49f, 0.5f, 0.53f}

Parameters:

ratios - the new brightness ratios

renderSegments

public void renderSegments(Graphics2D g2d,
                           Chart chart,
                           ChartModel m,
                           Point2D center,
                           float radius,
                           float[] angles)

Description copied from interface: PieSegmentRenderer2D

The method for rendering segments onto the supplied graphics context

Specified by:

renderSegments in interface PieSegmentRenderer2D

Parameters:

g2d - the Graphics2D context

chart - the chart

m - the model of interest

center - the center point (in pixel coordinates) of the rendered area

radius - the radius of the pie chart (in pixels)

angles - the angles (in degrees) of the respective segments of the model

renderSegments

public void renderSegments(Graphics g,
                           Chart chart,
                           ChartModel m,
                           Point center,
                           int radius,
                           int[] angles)

The method for rendering segments onto the supplied graphics context

Specified by:

renderSegments in interface PieSegmentRenderer

Parameters:

g - the Graphics context

chart - the chart

m - the model of interest

center - the center point (in pixel coordinates) of the rendered area

radius - the radius of the pie chart (in pixels)

angles - the angles (in degrees) of the respective segments of the model

renderOutlines

protected void renderOutlines(boolean isForSelection,
                              Graphics2D g2d,
                              Chart chart,
                              ChartModel model,
                              Point center,
                              int w,
                              int h,
                              int[] angles,
                              ChartStyle style)

Renders the outlines for a 3d pie chart, only when rollover is activated

Parameters:

isForSelection - there are two reasons or modes in which this method is invoked: one is for rendering outlines because it has been specified that outlines should always be displayed; and the other is for rendering an outline because it has been selected. If we call this method for the latter reason, this parameter is true.

g2d - the graphics context

chart - the chart component

model - the chart model for which we are rendering outlines

center - the center of the ellipse for which this is a segment

w - the width of the ellipse

h - the height of the ellipse

angles - an array of angles

style - style hints for the display (currently unused)

renderOutlines2D

protected void renderOutlines2D(boolean isForSelection,
                                Graphics2D g2d,
                                Chart chart,
                                ChartModel model,
                                Point2D center,
                                int w,
                                int h,
                                float[] angles,
                                ChartStyle style)
