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
{
					currentChart.setSubType( sNewSubType );
					EList axes = ( (Axis) ( (ChartWithAxes) currentChart ).getAxes( )
							.get( 0 ) ).getAssociatedAxes( );
					for ( int i = 0; i < axes.size( ); i++ )
					{
						( (Axis) axes.get( i ) ).setPercent( false );
						EList seriesdefinitions = ( (Axis) axes.get( i ) ).getSeriesDefinitions( );
						for ( int j = 0; j < seriesdefinitions.size( ); j++ )
						{
							Series series = ( (SeriesDefinition) seriesdefinitions.get( j ) ).getDesignTimeSeries( );
							series.setStacked( false );
						}
					}
				}
			}
			else if ( currentChart.getType( ).equals( BarChart.TYPE_LITERAL )
					|| currentChart.getType( ).equals( StockChart.TYPE_LITERAL )
					|| currentChart.getType( ).equals( AreaChart.TYPE_LITERAL )
					|| currentChart.getType( ).equals( LineChart.TYPE_LITERAL ) )
			{
				currentChart.setSampleData( getConvertedSampleData( currentChart.getSampleData( ),
						currentChart.getType( )
								.equals( StockChart.TYPE_LITERAL ) ) );
				currentChart.setType( TYPE_LITERAL );
				( (Axis) ( (ChartWithAxes) currentChart ).getAxes( ).get( 0 ) ).setType( AxisType.LINEAR_LITERAL );
