I am trying hard to implement a charting extension to an app that i am developing : so my problem is that I have written some code (the boiler plate one) for doing this in BIRT.
At some place in the code, I have to link the dataset to a series and link the series to a seriesdefinition object which finally will be attached to the charts seriesDefinitions like this
RadarSeries radarSeries = RadarSeriesImpl.create();
radarSeries.setDataSet(numberDataValues);
radarSeries.setSeriesIdentifier("Number data values");
radarSeries.getLabel().setVisible(true);
where numberDataValues is an array of doubles. Then I create my seriesDefinition :
SeriesDefinition seriesDefinition = SeriesDefinitionImpl.create();
seriesDefinition.getSeriesPalette().shift(0);
But then, here comes the time when I have to LINK my radarSeries to the seriesDefinition like this :
seriesDefinition.getSeriesDefinitions().add(radarSeries);
THE PROBLEM : I don't have the getSeriesDefinitions() method when trying to call it from code (doing a Ctrl+Space in Eclipse).
Needless to say that I can't call the getSeriesDefinitions() method on myChart object :
myChart.getSeriesDefinitions().add(seriesDefinition);
FOR YOUR INFORMATION : I have included my birt jars manually in my local maven repository and the details of these dependencies are :
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>engineapi</artifactId>
<version>${birtVersion}</version>
</dependency>
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>coreapi</artifactId>
<version>${birtVersion}</version>
</dependency>
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>scriptapi</artifactId>
<version>${birtVersion}</version>
</dependency>
<dependency>
<groupId>org.eclipse.birt</groupId>
<artifactId>chartengineapi</artifactId>
<version>${birtVersion}</version>
</dependency>
where ${birtVersion} = 2.6.2
here is a link to the official example of the 2.6.2 release of birt about RadarChart : Radar chart official release example
Can somebody help me ? I really can't believe I didn't found out how to do this in a 3days google search session : that not serious! ... given its popularity and its power, I think they should have invested more effort in the documentation ...
@Birt guyz (if any) > sorry to be so dramatic guys, but I really think that the doc side really sucks ... I hope to be able to help you on this (really, I do)
Here is the code :

PlatformConfig platformConfig = new PlatformConfig();
platformConfig.setProperty("STANDALONE", true);
// Creating Chart Engine
ChartEngine chartEngine = ChartEngine.instance(platformConfig);
IGenerator iGenerator = chartEngine.getGenerator();
if(iGenerator == null)
System.out.println("IGenerator NULL");
else
System.out.println("IGenerator NOT NULL");
try {
// iDeviceRenderer = chartEngine.getRenderer("dv.PNG");
iDeviceRenderer = chartEngine.getRenderer("dv.GIF");
iDisplayServer = iDeviceRenderer.getDisplayServer();
} catch (Exception e) {
e.printStackTrace();
}
// Creating Chart
ChartWithoutAxes radarChart = ChartWithoutAxesImpl.create( );
radarChart.setDimension( ChartDimension.TWO_DIMENSIONAL_LITERAL );
radarChart.setType(Radar.TYPE_LITERAL); //$NON-NLS-1$
radarChart.setSubType( "Standard Radar Chart" ); //$NON-NLS-1$
// Plot
radarChart.setSeriesThickness( 10 );
// Legend
Legend lg = radarChart.getLegend( );
lg.getOutline( ).setVisible( true );
// Title
radarChart.getTitle( )
.getLabel( )
.getCaption( )
.setValue( "Radar Chart" );//$NON-NLS-1$
try {
if(radarChart != null)
System.out.println("RADAR CHART NOT NULL");
else
System.out.println("RADAR CHART NULL!!!");
// PREPARE PHASE
context = Generator.instance().prepare(radarChart, null, null, ULocale.getDefault());
if(context == null)
System.out.println("CONTEXT NULL ");
else
System.out.println("CONTEXT NOT NULL");
//BIND PHASE : fetch data from DB
NumberDataSet numberDataValues = NumberDataSetImpl.create( new double[]{
54, 21, 75, 91, 37
} );
// Radar series
RadarSeries radarSeries = RadarSeriesImpl.create();
radarSeries.setDataSet(numberDataValues);
radarSeries.setSeriesIdentifier("Number data values");
radarSeries.getLabel().setVisible(true);
SeriesDefinitionImpl seriesDefinition = (SeriesDefinitionImpl) SeriesDefinitionImpl.create();
seriesDefinition.getSeriesPalette().shift(0);
// ERROR HERE : can't call the method
seriesDefinition.getSeriesDefinitions()
// RENDERING PHASE
if(iDisplayServer == null)
System.out.println("DISPLAY SERVER NULL");
else
System.out.println("DISPLAY SERVER NOT NULL");
GeneratedChartState generatedChartState = iGenerator.build(iDisplayServer, radarChart, null, null, context);
iGenerator.render(iDeviceRenderer, generatedChartState);
} catch (Exception e) {
e.printStackTrace();
}
}
EDIT + SOLUTION
Sorry for the delay : I should have posted this answer earlier to mark this question as solved. Just use the RCP report designer to create your report document. Copy ReportEngine/lib/*jars to your /WEB-INF/lib; also create a platform/ directory under WEB-INF/ and copy BIRT ReportEngine configuration/ and plugins/ directories under the newly created WEB-INF/platform/ folder. Now with the *.rptdesign file that you have created in your BIRT RCP designer tool, you will have to use the BIRT API which will allow you to interact with your report...
