How to generate chart image without invoking JFrame

[mrburns2002]

Hi,

as I would like to run JFree Chart on the server without X11, I need to avoid invoking the JPanel window:

My code is like this:

Code: Select all

        JFreeChart jfreechart = createChart(dataset,title,avg_p_value);
        ChartPanel chartPanel = new ChartPanel(jfreechart);
        chartPanel.setPreferredSize(new java.awt.Dimension(635, 405));
        chartPanel.setMouseZoomable(true, false);
        setContentPane(chartPanel);

How can I bypass this this ChartPanel stuff? I need a silent generation of the chart without creating a window.

Any ideas?

It depends what you mean by "silent generation of the chart". JFreeChart is generally pretty quiet as it goes about its work.

The JFreeChart class has various createBufferedImage() methods you could use.
