I have a Jfreechart timeseries line graph running well.

After I add

frame.getChartPanel().setMouseWheelEnabled(true);
frame.getChartPanel().setMouseZoomable(true, false);

to the code, it can zoom in and out by the mouse wheel, but the problem is when I zoom out, it doesn't have a limit and many blank spaces get into the graph and the line gets smaller and smaller.

Is there a way to set a boundary for the graph so when I zoom out it could only get back to the same size as it generates?

Additional information: the solution in this post JFreeChart Maximum Zoom Out doesn't work in my case

If `restoreAutoBounds()` isn't sufficient, you'll probably need a custom `MouseWheelHandler` in `ChartPanel`. – trashgod Jan 22 '17 at 13:39
@trashgod is there an example of how to customing it? I can't find mouseWheelHandler method – newbimyth Jan 22 '17 at 19:24
The class `org.jfree.chart.MouseWheelHandler` is included in the distribution. – trashgod Jan 23 '17 at 04:00
