Generic parameters allow compile-time type checking. Primitive types, such as int and double , are not valid generic parameter types. Instead, use the corresponding wrappers types, such as Integer or Double . For more flexibility, code to the interface type, e.g. List<Integer> or List<Double> .

Bug 3446965, TimeSeries Bug, fixed in r2441.

You might try preparing an sscce using synthetic data. The word "jumpy" suggests a failure to pack() the enclosing Window , which leaves the enclosed Container invalid. The word "sometimes" suggests a failure to construct the GUI on the event dispatch thread . Update: For reference, the JTabbedPane ...

Yes,I tested BarChartDemo1, too. Results vary by platform, but I saw a decrease proportional to the size of the buffer.

Profile , profile, profile. I used the alternate constructor shown below to explore. Telling ChartPanel not to useBuffer proved helpful. Normally, you can't force GC, but a profiler can use JVM TI to Force Garbage Collection as required. public BarChartDemo1(String title) { super(title); CategoryDa...

I profiled org.jfree.chart.demo.BarChartDemo1, but I only saw 7.4 K bytes for classes belonging to org.jfree.

One approach is cited here.

You can use a paging approach, illustrated here.

If you mean this approach, also consider, GridLayout(0, 1) or BoxLayout. Given a suitable cell renderer, JList or JTable are yet more flexible.

You may need to add a starting data point to each series before stating up. For expedience, I just called the timer's action listener, but you'll want to do something more appropriate. dataGenerator = new DataGenerator(tic * 1000); dataGenerator.actionPerformed(null); A few additional notes: Build y...

Sorry, I haven't tried them all. Why not try a simple one like XYPointerAnnotation with an arbitrary y value for each x. As you mention shapes, two example using XYShapeAnnotation are cited here.

You might look over the org.jfree.chart.annotations package.

It's not clear why you call centerFrameOnScreen() , setVisible() and pack() in a loop, but setVisible() is the likely culprit. None are necessary, as the view listens for changes to the model by default. Updating the model from a thread other than the event dispatch thread is also incorrect; instead...
