JFreeChart : obtain data source value on mouse click

Question

I have a JFreeChart instance that displays process memory status, initialized as follows:

m_data = new TimeSeriesCollection();
TimeSeries vmsize = new TimeSeries("VMSize");
TimeSeries resident = new TimeSeries("Resisdent");
TimeSeries shared = new TimeSeries("Shared memory");
TimeSeries code = new TimeSeries("Code");
TimeSeries data = new TimeSeries("Data");
m_data.addSeries(vmsize);
m_data.addSeries(resident);
m_data.addSeries(shared);
m_data.addSeries(code);
m_data.addSeries(data);
JFreeChart chart = ChartFactory.createTimeSeriesChart("Memory usage", "Time", "Size", m_data, true, true, false);
m_chart = new ChartPanel(chart);

Later I add values to each TimeSeries in the TimeSeriesCollection. I would like to somehow know - when the user clicks on the Chart - either what time associated with that columm, or even better - what is the index of the value.

I looked at the JFreeChart and ChartMouseListener classes, but I could not figure out how to do that (also the documentation of JFreeChart is annoyingly scarce, I guess they are trying to get people to buy their developer's guide).

Answer 1

hmm should work, if you replace the last two lines by something like this:

ChartPanel panel=new ChartPanel(ChartFactory.createTimeSeriesChart("Memory usage", "Time", "Size", m_data, true, true, false)));
panel.addChartMouseListener(new ChartMouseListener(){
    void chartMouseClicked(ChartMouseEvent e){
        [...do something on click...]
    }
    void chartMouseMoved(ChartMouseEvent e){
        [...do something on move...]
    }
});
return panel;
