Uwe, I think that Mark means a notification mechanism when data
gets added to or removed from his QwtData class.

For that, the data class needs a pointer to the curve to call
curve->curveChanged() on each change of the internal state of
the data class (note: curveChanged() is protected, so one has
to work around this)
