Hi All,
I am using JSP and servlet technology for making graphs.
Below please find my jsps,
Display.jsp

final double[][] data = new double[][]{{210, 300, 320, 265, 299},{200, 304, 201, 201, 340}};
final CategoryDataset dataset = DatasetUtilities.createCategoryDataset("Team ", "", data);
final JFreeChart chart = ChartFactory.createAreaChart("Area Chart", "", "Value", dataset, PlotOrientation.VERTICAL,true, true, false);
final CategoryPlot plot = chart.getCategoryPlot();
plot.setForegroundAlpha(0.5f);
chart.setBackgroundPaint(new Color(249, 231, 236));
try {
final ChartRenderingInfo info = new ChartRenderingInfo(new StandardEntityCollection());
//String sname = request.getRealPath("/");
//sname = sname.concat("web/areachart.png");
//out.println(sname);
//file = new File(sname);
//final File file1 = new File(sname);
File file1 = new File("../webapps/jspGraphFunction/web/areachart.png");
ChartUtilities.saveChartAsPNG(file1, chart, 600, 400, info);
} catch (Exception e) {
out.println(e);
}

</html>Now its giving the below error for the bolded statement in the code:
The method createAreaChart(String, String, String, CategoryDataset, PlotOrientation,
boolean, boolean, boolean) in the type ChartFactory is not applicable for the arguments
(String, String, String, CategoryDataset, PlotOrientation, boolean, boolean, boolean)
On net only this way of using the jfreechart is given
I have included the two jars Jfreechart... and jcommon in my lib folder.
Pls suggest,
Chandan
