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
.clear( );
				
				( (SeriesDefinition) ( (Axis) ( (ChartWithAxes) currentChart ).getAxes( )
						.get( 0 ) ).getSeriesDefinitions( ).get( 0 ) ).getSeries( )
						.add( series );
				
				EList seriesdefinitions = ( (Axis) ( (Axis) ( (ChartWithAxes) currentChart ).getAxes( )
						.get( 0 ) ).getAssociatedAxes( ).get( 0 ) ).getSeriesDefinitions( );
				for ( int j = 0; j < seriesdefinitions.size( ); j++ )
				{
					series = ( (SeriesDefinition) seriesdefinitions.get( j ) ).getDesignTimeSeries( );
					series = getConvertedSeries( series );
					series.setStacked( false );
					
					( (SeriesDefinition) seriesdefinitions.get( j ) ).getSeries( )
							.clear( );
					
					( (SeriesDefinition) seriesdefinitions.get( j ) ).getSeries( )
							.add( series );
				}
			}
			else
			{
				return null;
			}
			currentChart.getLegend( )
					.setItemType( LegendItemType.SERIES_LITERAL );
			currentChart.getTitle( )
					.getLabel( )
					.getCaption( )
