[jCharts-users] Help: Combo chart with point chart

[Zelgadis <zel...@ya...>]

I'm using jChart 0.7.5 and I've a problem with combo
charts. If use a point chart with a legend I receive
an index out of bounds exception.

This is my code:

  public void service(HttpServletRequest request,
                      HttpServletResponse response)
throws
              ServletException, IOException {
  try {

       String[] xAxisLabels= { "1998", "1999", "2000",
"2001", "2002", "2003", "2004" };
       String xAxisTitle= null;
       String yAxisTitle= null;
       String title= null;
       DataSeries dataSeries = new DataSeries(
xAxisLabels, xAxisTitle, yAxisTitle, title );

       double[][] data1 = {{1,2,3,4,5,6,7}};
       String[] legendLabels= {"test_area"}; 
       Paint[] paints= { Color.blue};

       AreaChartProperties areaChartProperties= new
AreaChartProperties();
       AxisChartDataSet axisChartDataSet= new
AxisChartDataSet( data1, legendLabels, paints,
ChartType.AREA, areaChartProperties );
       dataSeries.addIAxisPlotDataSet(
axisChartDataSet );

       double[][] data2 = {{1,2,3,4,5,6,7}};
       legendLabels = new String[]{"test_point"};
       paints = new Paint[]{ Color.red };

       Shape[] shapes= {
PointChartProperties.SHAPE_CIRCLE };
       boolean[] fillPointFlags = {true};
       PointChartProperties pointChartProperties= new
PointChartProperties(shapes, fillPointFlags, paints);
       axisChartDataSet = new AxisChartDataSet( data2,
legendLabels, paints, ChartType.POINT,
pointChartProperties );
       dataSeries.addIAxisPlotDataSet(
axisChartDataSet );

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

       AxisChart axisChart= new AxisChart( dataSeries,
chartProperties, axisProperties, legendProperties,
500, 360 );

       ServletEncoderHelper.encodeJPEG13(axisChart,
1.0f, response);
     }
      catch (Throwable throwable) {
        throwable.getMessage();
        throwable.printStackTrace();
     }
  }


When I encode I receive:
java.lang.IndexOutOfBoundsException: Index: 1, Size: 1

I have this problem only when I use a point chart.
If I use a LineChart instead of point chart the code
works well



I think there is a problem with the legend, in fact if
I use:

LegendProperties legendProperties = null;

instead of

LegendProperties legendProperties = new
LegendProperties();

the code works well


Is it a bug or am I wrong?
Can someone help me?
Thank you.
