Problem with StackedXYArea Chart - Please Help!!!

[lukkumar]

Hi,
I was trying a demo application for StackedXYArea Chart and I have observed that
1. there was a white gap of stack between the first and second series and 2. there seems to be a line connecting for the last series and it is visible on the chart.
I want to get rid of above two...

Here's the code

public class StackedXYAreaChartDemo extends ApplicationFrame {

public StackedXYAreaChartDemo(String title) {

super(title);

SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy", Locale.UK);
XYSeries series1 = new XYSeries("Series 1", true, false);
XYSeries series2 = new XYSeries("Series 2", true, false);
XYSeries series3 = new XYSeries("Series 3", true, false);
XYSeries series4 = new XYSeries("Series 4", true, false);
try {
series1.add(sdf.parse("01-Aug-2002").getTime(), 101923);
series1.add(sdf.parse("02-Aug-2002").getTime(), 113125);
series1.add(sdf.parse("05-Aug-2002").getTime(), 122148);
series1.add(sdf.parse("06-Aug-2002").getTime(), 117434);
series1.add(sdf.parse("07-Aug-2002").getTime(), 133256);
series1.add(sdf.parse("08-Aug-2002").getTime(), 157654);
series1.add(sdf.parse("09-Aug-2002").getTime(), 195356);
series1.add(sdf.parse("12-Aug-2002").getTime(), 122567);

series2.add(sdf.parse("01-Aug-2002").getTime(), 32355);
series2.add(sdf.parse("02-Aug-2002").getTime(), 28543);
series2.add(sdf.parse("05-Aug-2002").getTime(), 29665);
series2.add(sdf.parse("06-Aug-2002").getTime(), 34567);
series2.add(sdf.parse("07-Aug-2002").getTime(), 32453);
series2.add(sdf.parse("08-Aug-2002").getTime(), 29455);
series2.add(sdf.parse("09-Aug-2002").getTime(), 28558);
series2.add(sdf.parse("12-Aug-2002").getTime(), 31084);

series3.add(sdf.parse("01-Aug-2002").getTime(), 45344);
series3.add(sdf.parse("02-Aug-2002").getTime(), 43222);
series3.add(sdf.parse("05-Aug-2002").getTime(), 44567);
series3.add(sdf.parse("06-Aug-2002").getTime(), 46435);
series3.add(sdf.parse("07-Aug-2002").getTime(), 42538);
series3.add(sdf.parse("08-Aug-2002").getTime(), 39553);
series3.add(sdf.parse("09-Aug-2002").getTime(), 44565);
series3.add(sdf.parse("12-Aug-2002").getTime(), 46548);

series4.add(sdf.parse("01-Aug-2002").getTime(), 55437);
series4.add(sdf.parse("02-Aug-2002").getTime(), 55745);
series4.add(sdf.parse("05-Aug-2002").getTime(), 52523);
series4.add(sdf.parse("06-Aug-2002").getTime(), 48563);

renderer.setOutline(true);

XYPlot plot = new XYPlot(dataset, xAxis, yAxis, renderer);
plot.setForegroundAlpha(0.65f);

yAxis.configure();

JFreeChart chart = new JFreeChart(null, JFreeChart.DEFAULT_TITLE_FONT, plot, true);




return chart;
}

public static void main(String[] args) {
StackedXYAreaChartDemo demo = new StackedXYAreaChartDemo("Stacked Area XY Chart Demo");
demo.pack();
RefineryUtilities.centerFrameOnScreen(demo);
demo.setVisible(true);
}

}



Please refer to the code above and see if I have missed any thing.

Definitely a bug. Thanks for the report, and especially the demo code. I filed it in the bug tracker so I can come back to it after I finish updating the web site and docs for the 1.0.6 release which just went up:
