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
sdX.getSeriesPalette( ).update( 0 );
		( (Axis) newChart.getAxes( ).get( 0 ) ).getSeriesDefinitions( )
				.add( sdX );
		newChart.getTitle( ).getLabel( ).getCaption( ).setValue( CHART_TITLE ); 
		( (Axis) ( (Axis) newChart.getAxes( ).get( 0 ) ).getAssociatedAxes( )
				.get( 0 ) ).setOrientation( Orientation.VERTICAL_LITERAL );
		( (Axis) ( (Axis) newChart.getAxes( ).get( 0 ) ).getAssociatedAxes( )
				.get( 0 ) ).setType( AxisType.LINEAR_LITERAL );
		SeriesDefinition sdY = SeriesDefinitionImpl.create( );
		sdY.getSeriesPalette( ).update( 0 );
		Series orthogonalSeries = ScatterSeriesImpl.create( );
		orthogonalSeries.getLabel( ).setVisible( true );
		( (ScatterSeries) orthogonalSeries ).setStacked( false );
		sdY.getSeries( ).add( orthogonalSeries );
		( (Axis) ( (Axis) newChart.getAxes( ).get( 0 ) ).getAssociatedAxes( )
				.get( 0 ) ).getSeriesDefinitions( ).add( sdY );
		if ( sSubType.equalsIgnoreCase( STANDARD_SUBTYPE_LITERAL ) )
		{
			newChart.setDimension( ChartDimension.TWO_DIMENSIONAL_LITERAL );
		}
		addSampleData( newChart );
		return newChart;
	}
	private void addSampleData( Chart newChart )
	{
		SampleData sd = DataFactory.eINSTANCE.createSampleData( );
		sd.getBaseSampleData( ).clear( );
		sd.getOrthogonalSampleData( ).clear( );
		
		BaseSampleData sdBase = DataFactory.eINSTANCE.createBaseSampleData( );
