Bug 117149 Add additional datapoint markers
I would like to propose adding additional datapoint markers. Attached is a set of markers I would like supported.
chart/org.eclipse.birt.chart.ui.extension/src/org/eclipse/birt/chart/ui/swt/type/ScatterChart.java
sdBase.setDataSetRepresentation( "3,9,-2" ); 
		sd.getBaseSampleData( ).add( sdBase );
		
		OrthogonalSampleData oSample = DataFactory.eINSTANCE.createOrthogonalSampleData( );
		oSample.setDataSetRepresentation( "15,-4,12" ); 
		oSample.setSeriesDefinitionIndex( 0 );
		sd.getOrthogonalSampleData( ).add( oSample );
		/*
		 * OrthogonalSampleData oSample2 =
		 * DataFactory.eINSTANCE.createOrthogonalSampleData();
		 * oSample2.setDataSetRepresentation("2,27,35");
		 * oSample2.setSeriesDefinitionIndex(0);
		 * sd.getOrthogonalSampleData().add(oSample2);
		 */
		newChart.setSampleData( sd );
	}
	private Chart getConvertedChart( Chart currentChart, String sNewSubType,
			Orientation newOrientation, String sNewDimension )
	{
		Chart helperModel = (Chart) EcoreUtil.copy( currentChart );
		if ( ( currentChart instanceof ChartWithAxes ) )
		{
			if ( currentChart.getType( ).equals( TYPE_LITERAL ) ) 
			
			
			
			{
				if ( !currentChart.getSubType( ).equals( sNewSubType ) )
