	private Series getConvertedSeries( Series series )
	{
		
		if ( series.getClass( )
				.getName( )
				.equals( "org.eclipse.birt.chart.model.component.impl.SeriesImpl" ) ) 
		{
			return series;
		}
		LineSeries lineseries = (LineSeries) LineSeriesImpl.create( );
		lineseries.getLineAttributes( ).setVisible( true );
		lineseries.getLineAttributes( ).setColor( ColorDefinitionImpl.BLACK( ) );
		if ( !( series instanceof ScatterSeries ) )
		{
			Marker marker = AttributeFactory.eINSTANCE.createMarker( );
			marker.setSize( 5 );
			marker.setType( MarkerType.BOX_LITERAL );
			marker.setVisible( true );
			lineseries.setMarker( marker );
		}
		else
		{
			lineseries.setMarker( ( (ScatterSeries) series ).getMarker( ) );
		}
		
		lineseries.setLabel( series.getLabel( ) );
		if ( series.getLabelPosition( ).equals( Position.INSIDE_LITERAL )
