Method Summary

int	barWidthsPerCategory(CategoryDataset data) Returns the number of bar widths in each category (used to calculate the width of a single bar).
void	drawCategoryItem(java.awt.Graphics2D g2, java.awt.geom.Rectangle2D dataArea, CategoryPlot plot, ValueAxis axis, CategoryDataset data, int series, java.lang.Object category, int categoryIndex, java.lang.Object previousCategory) Draws the bar for a single (series, category) data item.
void	drawPlotBackground(java.awt.Graphics2D g2, CategoryPlot plot, java.awt.geom.Rectangle2D axisDataArea, java.awt.Shape dataClipRegion) Draws the background for the plot.
void	drawRangeMarker(java.awt.Graphics2D g2, CategoryPlot plot, ValueAxis axis, Marker marker, java.awt.geom.Rectangle2D axisDataArea, java.awt.Shape dataClipRegion) Draws a vertical line across the chart to represent the marker.
java.awt.geom.Rectangle2D	getAxisArea(java.awt.geom.Rectangle2D plotArea) Returns the area that the axes (and date) must fit into.
java.awt.Shape	getDataClipRegion(java.awt.geom.Rectangle2D dataArea) Returns the clip region...usually returns the dataArea, but some charts (e.g.
boolean	hasItemGaps() Returns true to indicate that this renderer does allow for gaps between items.

Field Detail

effect3d

protected double effect3d

The size of the 3D effect (in pixels).

Constructor Detail

HorizontalBarRenderer3D

public HorizontalBarRenderer3D()

Default constructor.

HorizontalBarRenderer3D

public HorizontalBarRenderer3D(com.jrefinery.chart.tooltips.CategoryToolTipGenerator toolTipGenerator,
                               double effect3d)

Constructs a new renderer.

Method Detail

hasItemGaps

public boolean hasItemGaps()

Returns true to indicate that this renderer does allow for gaps between items.

Overrides:

hasItemGaps in class HorizontalBarRenderer

barWidthsPerCategory

public int barWidthsPerCategory(CategoryDataset data)

Returns the number of bar widths in each category (used to calculate the width of a single bar).

Overrides:

barWidthsPerCategory in class HorizontalBarRenderer

Parameters:

data - The data.

getAxisArea

public java.awt.geom.Rectangle2D getAxisArea(java.awt.geom.Rectangle2D plotArea)

Returns the area that the axes (and date) must fit into.

Often this is the same as the plotArea, but sometimes a smaller region should be used (for example, the 3D charts require the axes to use less space in order to leave room for the 'depth' part of the chart).

Specified by:

getAxisArea in interface CategoryItemRenderer

Overrides:

getAxisArea in class AbstractCategoryItemRenderer

Parameters:

plotArea - The plot area.

getDataClipRegion

public java.awt.Shape getDataClipRegion(java.awt.geom.Rectangle2D dataArea)

Returns the clip region...usually returns the dataArea, but some charts (e.g. 3D) have non rectangular clip regions.

Specified by:

getDataClipRegion in interface CategoryItemRenderer

Overrides:

getDataClipRegion in class AbstractCategoryItemRenderer

Parameters:

dataArea - The data area.

drawPlotBackground

public void drawPlotBackground(java.awt.Graphics2D g2,
                               CategoryPlot plot,
                               java.awt.geom.Rectangle2D axisDataArea,
                               java.awt.Shape dataClipRegion)

Draws the background for the plot.

For most charts, the axisDataArea and the dataClipArea are the same. One case where they are different is the 3D-effect bar charts...here the data clip area extends above and to the right of the axisDataArea.

Specified by:

drawPlotBackground in interface CategoryItemRenderer

Overrides:

drawPlotBackground in class AbstractCategoryItemRenderer

Parameters:

g2 - The graphics device.

plot - The plot.

axisDataArea - The area inside the axes.

dataClipArea - The data clip area.

drawRangeMarker

public void drawRangeMarker(java.awt.Graphics2D g2,
                            CategoryPlot plot,
                            ValueAxis axis,
                            Marker marker,
                            java.awt.geom.Rectangle2D axisDataArea,
                            java.awt.Shape dataClipRegion)

Draws a vertical line across the chart to represent the marker.

Specified by:

drawRangeMarker in interface CategoryItemRenderer

Overrides:

drawRangeMarker in class HorizontalBarRenderer

Parameters:

g2 - The graphics device.

plot - The plot.

axis - The value axis.

marker - The marker line.

axisDataArea - The axis data area.

dataClipRegion - The data clip region.

drawCategoryItem

public void drawCategoryItem(java.awt.Graphics2D g2,
                             java.awt.geom.Rectangle2D dataArea,
                             CategoryPlot plot,
                             ValueAxis axis,
                             CategoryDataset data,
                             int series,
                             java.lang.Object category,
                             int categoryIndex,
                             java.lang.Object previousCategory)

Draws the bar for a single (series, category) data item.

Specified by:

drawCategoryItem in interface CategoryItemRenderer

Overrides:

drawCategoryItem in class HorizontalBarRenderer

Parameters:

g2 - The graphics device.

dataArea - The data area.

plot - The plot.

axis - The range axis.

data - The data.

series - The series number (zero-based index).

category - The category.

categoryIndex - The category number (zero-based index).

previousCategory - The previous category.
