JFreeChart in Applet: Problems with refreshing chart

Thread view:

scifluent@gmail.com - 19 Apr 2007 18:03 GMT

I've created an applet and then added a JFreechart ChartPanel to it.

jContentPane.add(myChartPanel);

myChartPanel is a member variable of my applet

and I see the plot just fine. Then I change the chart by setting
the myChartPanel to a new ChartPanel

myChartPanel = ChartPanelCreator.getChartPanel();

but the chart does not refresh in my applet.

I've tried jContentPane.repaint(); but no...

Suggestions?

>Suggestions?

- Don't practice GUI development in applets.
- Avoid applets until you are very experienced.
- Prefer web start launched applications to applets.
- Produce an SSCCE* that shows this behaviour
(preferably one that does not require JFreeChart to
show the effect you are seeing).
