I try to build my LineChart completely in the bean code. Caption and legends of the charts appear but no axes, grid lines or data lines.
I guess one important problem is the data mapping, which I don't really know how to perform it in bean's code.

JSF code is only this: 
...
<ig:chart id="chart4" binding="#{myChart.chart}" />
...

JAVA Bean code is:

private void initChart() {
  if (chart == null)  chart = new Chart();
  FacesContext context = FacesContext.getCurrentInstance();
  Application application = context.getApplication();
  MethodBinding dataPointListener1 = application.createMethodBinding(
  "#{myChart.processDataPoint}", new Class[ { javax.faces.event.ActionEvent.class });
  chart.setDataPointListener(dataPointListener1);
  chart.setChartType("Line");
  chart.setGroupType("Stack100");
  chart.setProjectionType("2D");
  chart.setStyle("width: 420; height: 320");
  Caption caption = new Caption();
  caption.setCaption("2D Stack100 Line Chart 1");
  caption.setPosition("top");
  chart.setCaption(caption);
  Legend legend = new Legend();
  legend.setPosition("right");
  legend.setAutoItems(true);
  chart.setLegend(legend);
  Axis xAxis = new Axis();
  xAxis.setType(AxisType.X.toString());
  xAxis.setAutoRange(true);
  xAxis.setAutoRangeSnap(false);
  xAxis.setAutoTickMarks(true);
  xAxis.setAutoGridLines(true);
  chart.getChildren().add(xAxis);
  xAxis.setParent(chart);
  Axis yAxis = new Axis();
  yAxis.setType("y");
  yAxis.setAutoRange(true);
  yAxis.setAutoRangeSnap(true);
  yAxis.setAutoTickMarks(true);
  yAxis.setAutoGridLines(true);
  chart.getChildren().add(yAxis);
  yAxis.setParent(chart);
  for (int i = 0; i < 3; ++i) {
    Series series = new Series();
    series.setChartType(ChartType.LINE.toString());
    NumbersSource data = new NumbersSource();
    ScalarDataModel model = new ScalarDataModel();
    model.setWrappedData(data.getSparse0());
    series.setDataSource(model);

   // series.setDataMapping( "value: column0" );

   chart.getChildren().add(series);
  }
  chart.dataBind(context);
}

- If I activate the line with series.setDataMapping I get the follwing error:

>> WARN Coercions:513 - Ausnahmefehler beim Versuch, String "column0" in Typ "java.lang.Integer" zu konvertieren
>> ERROR ArraySuffix:181 - Dem Operator "." wurde ein Indexwert vom Typ "java.lang.String" zur Anwendung auf eine Liste oder einen Array

>>17:49:47,593 DEBUG ValueBindingImpl:188 - getValue Evaluation threw exception:

>> at com.sun.faces.el.impl.ArraySuffix.evaluate(ArraySuffix.java:183)

The code of the original trial (LineChart) is:

<ig:series markerBulletVisible="true" legendCaption="#{webchart_numbersSource.name1}"
   dataMapping="value: column0; tooltipCaption: caption" dataSource="#{webchart_numbersSource.sparse1}" />
<ig:series markerBulletVisible="true" legendCaption="#{webchart_numbersSource.name2}"
   dataMapping="value: column0; tooltipCaption: caption" dataSource="#{webchart_numbersSource.sparse2}" />

So my questions are:
- Does anybody know if the missing data mapping is the problem, that no data and axes is displayed?
- How can I set a valid DataMapping in above listed code?
