Class StackedBarChartRenderer

java.lang.Object
  com.approximatrix.charting.render.AbstractChartRenderer
      com.approximatrix.charting.render.StackedBarChartRenderer

All Implemented Interfaces:

Renderer

public class StackedBarChartRenderer
extends AbstractChartRenderer

This renderer creates a stacked BarChart. This will only work on a ChartDataModel with non-numeric x-axis values, because I couldn't make any sense out of a bar chart with a numeric x-axis like in a line chart.

Constructor Detail

StackedBarChartRenderer

public StackedBarChartRenderer(CoordSystem cs,
                               AbstractChartDataModel model)

Creates new StackedBarChartRenderer

Parameters:

cs - the ClassicCoordSystem used to translate into pixel space

model - the DataModel that should be rendered

StackedBarChartRenderer

public StackedBarChartRenderer(CoordSystem cs,
                               AbstractChartDataModel model,
                               float boxWidth)

Creates new StackedBarChartRenderer

Parameters:

cs - the ClassicCoordSystem used to translate into pixel space

model - the DataModel that should be rendered

boxWidth - a value between 0.0 and 1.0 representing how much of the alloted space each box should consume. If 1.0 is passed, then each box will completely fill it's allotted space, alternately I suggest you don't pass 0.0

Method Detail

renderChart

public void renderChart(java.awt.Graphics2D g)

Finally renders the Object in the Graphics object.

Specified by:

renderChart in class AbstractChartRenderer

Parameters:

g - the Graphics2D object in which to render
