Hallo,

leider kann ich kein einfaches Diagramm in Netbeans in einem Modul darstellen:

Code :

1 2 3 4 5 6 7 8 9 10 11 12 13 14

private void jButton9MouseClicked(java.awt.event.MouseEvent evt) {                                           XYSeries series = new XYSeries("Maschine1");     series.add(2000.0, 50.0);     series.add(2003.0, 20.0);       XYDataset xyDataset = new XYSeriesCollection(series);     JFreeChart chart = ChartFactory.createXYLineChart("Amortisationsdauer", "Jahre", "Kosten",             xyDataset, PlotOrientation.VERTICAL, true, true, false);     ChartPanel p = new ChartPanel(chart);     jPanel1.add(p);     p.setSize(700, 700);     p.setVisible(true);   }

sobald ich den Button klicke bekomme ich folgende fehlermeldung, mit der ich leider nichts anfangen kann :

Code :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

hat jemand vielleicht einen Tipp? wenn ich das Diagramm in einem normalen Java Projekt erstelle klappt alles prima :

Code :

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

import org.jfree.chart.*; import org.jfree.chart.plot.PlotOrientation; import org.jfree.data.category.DefaultCategoryDataset; import org.jfree.data.general.DefaultPieDataset; import org.jfree.data.xy.*; import org.jfree.data.*;   public class xyLine {  public static void main(String arg[]){  chart();  }  public static void chart()    {         XYSeries series = new XYSeries("Maschine1");         series.add(2000.0, 50.0);           series.add(2003.0, 20.0);           XYDataset xyDataset = new XYSeriesCollection(series);         JFreeChart chart = ChartFactory.createXYLineChart("Amortisationsdauer", "Jahre", "Kosten",                 xyDataset, PlotOrientation.VERTICAL, true, true, false);         ChartFrame frame1 = new ChartFrame("XYLine Chart", chart);         frame1.setVisible(true);         frame1.setSize(500, 500);                             } }

Habe das Problem gefunden, musste alle jar Dateien von jfreecharts in das Modul packen
