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/LineChart.java
|| series.getLabelPosition( ).equals( Position.OUTSIDE_LITERAL ) )
		{
			lineseries.setLabelPosition( Position.ABOVE_LITERAL );
		}
		else
		{
			lineseries.setLabelPosition( series.getLabelPosition( ) );
		}
		lineseries.setVisible( series.isVisible( ) );
		if ( series.eIsSet( ComponentPackage.eINSTANCE.getSeries_Triggers( ) ) )
		{
			lineseries.getTriggers( ).addAll( series.getTriggers( ) );
		}
		if ( series.eIsSet( ComponentPackage.eINSTANCE.getSeries_DataPoint( ) ) )
		{
			lineseries.setDataPoint( series.getDataPoint( ) );
		}
		if ( series.eIsSet( ComponentPackage.eINSTANCE.getSeries_DataDefinition( ) ) )
		{
			lineseries.getDataDefinition( ).add( series.getDataDefinition( )
					.get( 0 ) );
		}
		
		if ( series instanceof StockSeries )
		{
			lineseries.getLineAttributes( )
					.setColor( ( (StockSeries) series ).getLineAttributes( )
							.getColor( ) );
		}
		return lineseries;
