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/composites/MarkerIconDialog.java
for ( int i = 0; i < controls.length; i++ )
		{
			controls[i].dispose( );
		}
		
		switch ( type )
		{
			case URI_TYPE :
				swtichToURIType( );
				break;
			case LOCAL_TYPE :
				swtichToListType( );
				break;
		}
		inputArea.layout( );
	}
	private void swtichToURIType( )
	{
		Label title = new Label( inputArea, SWT.NONE );
		title.setLayoutData( new GridData( GridData.VERTICAL_ALIGN_BEGINNING ) );
		title.setText( Messages.getString( "MarkerIconDialog.Lbl.EnterURL" ) ); 
		uriEditor = new Text( inputArea, SWT.SINGLE | SWT.BORDER );
		uriEditor.setLayoutData( new GridData( GridData.FILL_HORIZONTAL ) );
		uriEditor.addModifyListener( this );
		Composite innerComp = new Composite( inputArea, SWT.NONE );
		innerComp.setLayoutData( new GridData( GridData.HORIZONTAL_ALIGN_END ) );
		GridLayout gl = new GridLayout( 2, false );
		gl.marginWidth = 0;
		gl.marginHeight = 0;
		gl.verticalSpacing = 2;
