[nebula-dev] New topic in forum Nebula, called XYGraph - how to draw data points with no connecting line?, by Patrik Suzzi

[forums-noreply]

Hallo, 

I am using Eclipse Nebula XYGraph for a Scientific Project. 

In my next graph I will need to display data points only and not the connecting line. 


I tried setting the line width to zero (0), but this is not working. 

trace.setLineWidth(0);

Any suggestion ?

       xyGraph = new XYGraph();
       xyGraph.primaryXAxis.setShowMajorGrid(true);
       xyGraph.primaryYAxis.setShowMajorGrid(true);     
       xyGraph.setBackgroundColor(ColorConstants.white);
                
       CircularBufferDataProvider traceDataProvider = new 
CircularBufferDataProvider(false);
       traceDataProvider.setBufferSize(1000);
       
       for(Node node : resultList){
                double x = node.getX();
                double y = node.getX();
                // add data point
        traceDataProvider.addSample(new Sample(x, y));
       }

       // create the trace
       Trace trace = new Trace("Trace1-XY Plot", xyGraph.primaryXAxis, 
xyGraph.primaryYAxis, traceDataProvider);
        
       // set trace property
       trace.setPointStyle(PointStyle.XCROSS);
                
       // How to NOT display the connecting line?
       trace.setLineWidth(0);

       // add the trace to xyGraph
       xyGraph.addTrace(trace);

Thanks in advance
