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/LineChart.java
SeriesDefinition sdY = SeriesDefinitionImpl.create( );
			sdY.getSeriesPalette( ).update( 0 );
			Series valueSeries = LineSeriesImpl.create( );
			valueSeries.getLabel( ).setVisible( true );
			( (LineSeries) valueSeries ).getMarker( ).setVisible( true );
			( (LineSeries) valueSeries ).setStacked( true );
			( (LineSeries) valueSeries ).setPaletteLineColor( true );
			sdY.getSeries( ).add( valueSeries );
			( (Axis) ( (Axis) newChart.getAxes( ).get( 0 ) ).getAssociatedAxes( )
					.get( 0 ) ).getSeriesDefinitions( ).add( sdY );
		}
		else if ( sSubType.equalsIgnoreCase( PERCENTSTACKED_SUBTYPE_LITERAL ) )
		{
			( (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 );
