Changing the line size of a JFreeChart chart

This is an example showing how to change the line size of a Java graph builded with JFreeChart library.

The example is using the version JFreeChart 1.0.13

...

private JFreeChart createChart(XYDataset dataset, ICarteira car) {

  // create the chart...

  final JFreeChart chart = ChartFactory.createTimeSeriesChart(

    car.getNome(), // title

    "Tempo", // x axis label

    "Valor", // y axis label

    dataset, // data

    true, // include legend

    true, // tooltips

    true // urls

    );




  XYPlot plot = chart.getXYPlot();




  // here we change the line size

  int seriesCount = plot.getSeriesCount();

  for (int i = 0; i < seriesCount; i++) {

   plot.getRenderer().setSeriesStroke(i, new BasicStroke(2));

  }

  // line size changed

 

  return chart;

 }
