Re: [jCharts-users] How to render Axis Charts

>did you look at the SwingDemo in the demo package?


Yes, I did look prior to posting my message.  I don't any difference 
between my code and the SwingDemo.java code.  What is my code missing?

    private void initComponents() throws ChartDataException, PropertyException
    {
       this.setSize( width, height );
       this.panel = new JPanel( true );
       this.panel.setSize( width, height );
       this.getContentPane().add( this.panel );
       this.setVisible( true );

       String[] xAxisLabels = { "1998", "1999", "2000", "2001",
                                "2002", "2003", "2004" };
       String xAxisTitle = "Years";
       String yAxisTitle = "Problems";
       String title = "Micro$haft at Work";
       DataSeries dataSeries = new DataSeries(xAxisLabels, xAxisTitle,
                                              yAxisTitle, title );

       double[][] data = new double[][]{ { 250, 45, -36, 66, 145, 80, 55 } };
       String[] legendLabels = { "Bugs" };
       Paint[] paints = {Color.blue};

       Stroke[] strokes = { LineChartProperties.DEFAULT_LINE_STROKE };
       Shape[]  shapes  = { PointChartProperties.SHAPE_CIRCLE };
       LineChartProperties lineChartProperties = new 
LineChartProperties(strokes, shapes
);

       AxisChartDataSet axisChartDataSet =
              new AxisChartDataSet(data, legendLabels, paints, ChartType.LINE,
                                   lineChartProperties );
       dataSeries.addIAxisPlotDataSet (axisChartDataSet);

       ChartProperties chartProperties   = new ChartProperties();
       AxisProperties axisProperties     = new AxisProperties();
       LegendProperties legendProperties = new LegendProperties();

       AxisChart axisChart= new AxisChart(dataSeries, chartProperties,
                                          axisProperties, legendProperties,
                                          450, 450);
       axisChart.setGraphics2D ( (Graphics2D) this.panel.getGraphics() );
       axisChart.render();
}
