public class GJBar
extends GJAbstractPlot

GJBar supports bar plots and histograms. GJBar is unusual in supporting swapping of data displayed along the x- and y-axes to support both vertical and horizontal bar charts.

• For vertical bars.
• The XData represent the offsets on the x-axis.
• the YData represent their heights.
• For horizontal bars.
• The XData represent the offsets on the y-axis.
• the YData represent their horizontal lengths.

This support is limited to the display of the bars through the x,y data pairs. If you want e.g. to add categories to an axis, you need to address those calls to the axis appropriate to the alignment so with horizontal bars, you should still call getYData().setCategory(...). However, the behaviour of the getDataRange() has been overridden to account for the alignment (which facilitates auto ranging of the axes).

Method Detail

createInstance

public static GJPlotInterface createInstance()

Factory method for creating a bar chart.

Returns:

the GJBar instance

paintPlot

public final void paintPlot(java.awt.Graphics2D g2)

Description copied from class: GJAbstractPlot

Note that this method is overloaded by all concrete sub-classes which should call this super-class method.

Specified by:

paintPlot in interface GJPlotInterface

Overrides:

paintPlot in class GJAbstractPlot

getDataRange

public final java.awt.geom.Rectangle2D getDataRange()

This overrides the super class method providing support for horizontal bars too by swapping the x- and y- data. The behaviour of other methods that call getDataRange will change as a consequence.

Specified by:

getDataRange in interface GJDataModelInterface<java.awt.geom.Rectangle2D,GJGraphInterface>

Overrides:

getDataRange in class GJAbstractPlot

Returns:
