All Implemented Interfaces:

BarRenderer, BarRenderer2D

public class DefaultBarRenderer
extends AbstractBarRenderer
implements BarRenderer2D

This renderer takes account of negative heights. If a negative height is supplied, then the y coordinate and height are adjusted so that the height becomes positive and the shape is paintable.

NOTE: Widths are currently assumed to be positive

There is one call to this method for each bar to be rendered in a bar chart.

Specified by:

renderBar in interface BarRenderer2D

Parameters:

g - the graphics context onto which the bar is drawn

chart - the chart object

m - the chart model from which the bar/point comes

p - the point of the model corresponding to the bar

isSelected - whether the bar is currently selected

hasRollover - whether the bar currently is under the mouse cursor

hasFocus - whether the bar currently has focus (not yet supported)

x - the x pixel coordinate for the top left of the bar

y - the y pixel coordinate for the top left of the bar

width - the width of the bar in pixels

height - the height of the bar in pixels
