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.

public boolean canParticipateInCombination( )

		return true;

	public void translateFrom( Series series, int iSeriesDefinitionIndex,
			Chart chart )
	{
		this.getLineAttributes( ).setVisible( true );
		this.getLineAttributes( ).setColor( ColorDefinitionImpl.BLACK( ) );
		if ( !( series instanceof ScatterSeries ) )
		{
			Marker marker = AttributeFactory.eINSTANCE.createMarker( );
			marker.setSize( 5 );
			marker.setType( MarkerType.BOX_LITERAL );
			marker.setVisible( true );
			this.setMarker( marker );
		}
		else
		{
			this.setMarker( ( (ScatterSeries) series ).getMarker( ) );
		}
		
		this.setLabel( series.getLabel( ) );
		if ( series.getLabelPosition( ).equals( Position.INSIDE_LITERAL )
				|| series.getLabelPosition( ).equals( Position.OUTSIDE_LITERAL ) )
		{
			this.setLabelPosition( Position.ABOVE_LITERAL );
