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.

currentSampleData.getOrthogonalSampleData( )
				.addAll( vNewOrthogonalSampleData );
		return currentSampleData;
	}
	private String getConvertedSampleDataRepresentation(
			String sOldRepresentation, boolean bStockSeries )
	{
		StringTokenizer strtok = new StringTokenizer( sOldRepresentation, "," ); 
		NumberFormat nf = NumberFormat.getNumberInstance( );
		StringBuffer sbNewRepresentation = new StringBuffer( "" ); 
		int iValueCount = 0;
		while ( strtok.hasMoreTokens( ) )
		{
			String sElement = strtok.nextToken( ).trim( );
			if ( sElement.startsWith( "'" ) ) 
			{
				sElement = sElement.substring( 1, sElement.length( ) - 1 );
			}
			if ( bStockSeries )
			{
				StringTokenizer strStockTokenizer = new StringTokenizer( sElement );
				sElement = strStockTokenizer.nextToken( ).trim( ).substring( 1 );
			}
			try
			{
				double dbl = nf.parse( sElement ).doubleValue( );
				sElement = String.valueOf( dbl );
			}
			catch ( ParseException e )
