Question

I would like to know how to refresh a chart if we want to change \"in live\" some piece of data. I mean for instance, I have a chart with a TaskSeries which appears on 3 yea

Answer 1

What worked with me was the following:

//reset with new dataset
chart().setDataset(dataset);
repaint the ChartPanel that contains the JFreeChart
chartPanel.repaint();
