Grouping in Stacked Bar Chart

[njrfrens]

Can any one inform me how to implement grouping while implementing StackedBar Chart using Jasper Reports...

Attached is the Sample Chart to be developed.

It can be done in JFreeChart by using GroupedStackedBarRenderer.

But I want to know how to do the same in Jasper Reports...

Hi njrfrens!

For acheving this u have to set ur series expression for US/Asia etc and Month/Product Combination in Category Expression.

This may help u....

Pls let me know if u find any other sol. for this.

below is the code to display GroupedStacked Bar chart using JFreeChart

Code:

public void generateStackedChart(OutputStream out, Object data) {	try {		JFreeChart chart = ChartFactory.createStackedBarChart(				"Alerts as % of Total Programs", "Alerts", "%",				getStackedDataSet(), 				PlotOrientation.VERTICAL, 				true, // include legend				false, // tooltips				false); // urls		GroupedStackedBarRenderer renderer = new GroupedStackedBarRenderer();				KeyToGroupMap map = new KeyToGroupMap("G1");				map.mapKeyToGroup("Facility 1(ONE)", "G1");				map.mapKeyToGroup("Facility 2(ONE)", "G1");				map.mapKeyToGroup("Facility 3(ONE)", "G1");				map.mapKeyToGroup("Facility 4(ONE)", "G1");								map.mapKeyToGroup("Facility 1(ALL)", "G2");				map.mapKeyToGroup("Facility 2(ALL)", "G2");				map.mapKeyToGroup("Facility 3(ALL)", "G2");				map.mapKeyToGroup("Facility 4(ALL)", "G2");								renderer.setSeriesToGroupMap(map); 								CategoryPlot plot = (CategoryPlot) chart.getPlot();				plot.setRenderer(renderer);						BufferedImage buffImg = chart.createBufferedImage(500, // width				375, // height				BufferedImage.TYPE_INT_RGB, // image type				null);		ImageIO.write(buffImg, "jpeg", out);	} catch (IOException e) {		e.printStackTrace();	}}private DefaultCategoryDataset getStackedDataSet() {	DefaultCategoryDataset dataset = new DefaultCategoryDataset();	// dataset.addValue(1.0, "Row 1", "Column 1");	dataset.addValue(10.0, "Facility 1(ONE)", "Jan 2008");	dataset.addValue(50.0, "Facility 1(ONE)", "Feb 2008");	dataset.addValue(30.0, "Facility 1(ALL)", "Jan 2008");	dataset.addValue(25.0, "Facility 1(ALL)", "Feb 2008");		dataset.addValue(20.0, "Facility 2(ONE)", "Jan 2008");	dataset.addValue(30.0, "Facility 2(ONE)", "Feb 2008");	dataset.addValue(20.0, "Facility 2(ALL)", "Jan 2008");	dataset.addValue(30.0, "Facility 2(ALL)", "Feb 2008");		dataset.addValue(20.0, "Facility 3(ONE)", "Jan 2008");	dataset.addValue(30.0, "Facility 3(ONE)", "Feb 2008");	dataset.addValue(20.0, "Facility 3(ALL)", "Jan 2008");	dataset.addValue(30.0, "Facility 3(ALL)", "Feb 2008");		dataset.addValue(20.0, "Facility 4(ONE)", "Jan 2008");	dataset.addValue(30.0, "Facility 4(ONE)", "Feb 2008");	dataset.addValue(20.0, "Facility 4(ALL)", "Jan 2008");	dataset.addValue(20.0, "Facility 4(ALL)", "Feb 2008");	return dataset;}

Hi njrfrens,

Have you been able to achieve your objective of grouping while implementing StackedBar Chart using Jasper Reports.

If yes, can you please explain the solution to me.

Thanks
