Jfreechart - Refresh a chart according to changing data

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

I had this issue too with an XYPlot. I found a workaround by resetting the dataset:

chart.getXYPlot().setDataset(chart.getXYPlot().getDataset());

that's crazy but it works...

Note: chart.setNotify(true) seems to do nothing.
