How do I remove the points in XYLineAndShapeRenderer?

Question

I'm making an application in Java using JFreeChart which shows an XY line chart. The problem is that it shows every point of the dataset on the lines, and I don't want to display these points. Any idea on how to remove the points or make them not visible?

This is a sample screenshot:

Here is the code:

JFrame frame = new JFrame();                
XYLineAndShapeRenderer renderer = new XYLineAndShapeRenderer();
renderer.setSeriesPaint(0, Color.RED);
renderer.setSeriesStroke(0, new BasicStroke(2.0f, 
BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND, 1.0f,
    new float[] { 2.0f, 4.0f }, 0.0f));
XYDataset ds = createDataset(i, p, capacity);
JFreeChart xylineChart = ChartFactory.createXYLineChart("", "", 
"", ds, PlotOrientation.VERTICAL, true, true, false);
XYPlot plot = xylineChart.getXYPlot();
plot.setDomainGridlinePaint(Color.BLACK);
plot.setRangeGridlinePaint(Color.BLACK);
plot.setBackgroundPaint(Color.WHITE);
plot.setRenderer(renderer);
ChartPanel cp = new ChartPanel(xylineChart);
frame.getContentPane().add(cp);

Can you update your question with code – Bombardon

What part of the code do you want to see? Because there's a lot of code unrelated with the chart and I don't want to post it all – Outstanding

only that used for graph generation – Bombardon

I think it was that one, if i don't mix it up with the legend(try it - if you had given a code I could have checked it ;) ): jfree.org/jfreechart/api/javadoc/org/jfree/chart/renderer/xy/… – Backbite

thaks, it worked – Outstanding

Answer 1

By default, the no-argument constructor of XYLineAndShapeRenderer "Creates a new renderer with both lines and shapes visible." To remove the points, you can

• Use the alternative constructor to specify the desired combination—lines without shapes, as shown here and in ChartFactory.createXYLineChart:

  XYLineAndShapeRenderer renderer = new XYLineAndShapeRenderer(true, false);
  

• Invoke setSeriesShapesVisible(), as @abhinavxeon suggests here and the author suggests here:

  renderer.setSeriesShapesVisible(0, false)
