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.engine/src/org/eclipse/birt/chart/model/type/impl/LineSeriesImpl.java
( (Axis) ( (ChartWithAxes) chart ).getAxes( ).get( 0 ) ).setCategoryAxis( true );
		}
		else
		{
			throw new IllegalArgumentException( Messages.getString( "error.invalid.argument.for.lineSeries", 
					new Object[]{
						chart.getClass( ).getName( )
					},
					Locale.getDefault( ) ) );
		}
		
		chart.setSampleData( getConvertedSampleData( chart.getSampleData( ),
				iSeriesDefinitionIndex ) );
	}
	private SampleData getConvertedSampleData( SampleData currentSampleData,
			int iSeriesDefinitionIndex )
	{
		
		
		
		EList osdList = currentSampleData.getOrthogonalSampleData( );
		for ( int i = 0; i < osdList.size( ); i++ )
		{
			if ( i == iSeriesDefinitionIndex )
			{
				OrthogonalSampleData osd = (OrthogonalSampleData) osdList.get( i );
				osd.setDataSetRepresentation( getConvertedOrthogonalSampleDataRepresentation( osd.getDataSetRepresentation( ) ) );
				currentSampleData.getOrthogonalSampleData( ).set( i, osd );
			}
		}
