add dropdown menu with Nebula XY graph [message #1730664]

Hello

I'm trying to have a dropdown menu with a mouse right click on a specific point but I don't know how to do (Is-it possible to do?)

I use this to draw my points.

CircularBufferDataProvider traceDataProvider = new CircularBufferDataProvider(false);
traceDataProvider.setBufferSize(size);
traceDataProvider.setCurrentXDataArray(x);
traceDataProvider.setCurrentYDataArray(y);

trace = new Trace("test", xyGraph.getPrimaryXAxis(), xyGraph.getPrimaryYAxis(), traceDataProvider);
      trace.setPointStyle(PointStyle.FILLED_DIAMOND);
      trace.setPointSize(10);
      trace.setTraceType(TraceType.POINT);
      trace.setAntiAliasing(false);

Thanks

Hi, with this code

canvas = new Canvas(parent, SWT.DOUBLE_BUFFERED);
LightweightSystem lws = new LightweightSystem(canvas);
xyGraph = new XYGraph();
lws.setContents(xyGraph);
Menu canvasPopupMenu = new Menu(canvas);
MenuItem deleteItem = new MenuItem(canvasPopupMenu, SWT.NONE);
...
