Hi,

A data acquisition program in Java, neat!!!

If you have subclassed AbstractGraphModel then fireGraphDataChanged()
is the correct method to use. (Note it has been renamed from
fireDataChanged() in recent versions). If you are using one of the
DefaultGraphModels then you should not be using fireGraphDataChanged()
at all, but a changeSeries() method. Further, fireGraphDataChanged()
should only be called from within the event-dispatching loop (see Java
tutorial). If you are calling it from another thread, you should be
using something like

SwingUtilities.invokeLater(new Runnable() {
public void run() {fireGraphDataChanged();}
});

or

EventQueue.invokeLater(new Runnable() {
public void run() {fireGraphDataChanged();}
});

see also invokeAndWait().

I hope this resolves your problem.

Regards,

Mark
