Re: [flexcoders] invalidateDisplayList()
In your updateDisplayList() function, you can add an if clause to detect which part should be redrawn.Something like :if( dotChanged ){ //do redraw}Jeremy.

when I have 1000 points on my chart, the draggable box is very
sluggish.
I thought a
control's updateDisplayList() would only be called if something on that actual
control changed?
Thanks,

RE: [flexcoders] invalidateDisplayList()
That's not really a suitable fix. The
invalidateDisplayList()/updateDisplayList() effectively does that already.
updateDisplayList() on gets called if it's been invalidated. My problem is that
when I call invalidateDisplayList() inside my charts annotation class, it also
causes my PlotSeries to be invalidated, and redraw.
I can work around it, but I'm not sure if this is supposed
to happen, or there is an error in my code. If calling invalidateDisplayList()
is supposed to invalidate the entire application tree (include parents, siblings
and children), then I will have to change my PlotSeries.updateDisplayList() to
draw to a new graphics object, and just feed that up unless I know the data has
changed. I'm not convinced the behaviour I'm seeing is correct though
:-(
Surely invalidating one object should just cause itself
(and children) to be redrawn?

Re: [flexcoders] invalidateDisplayList()
Kinda weird, this is my understaning too, but I never dig deep enough into those charting widgets, maybe things are different in there.Have you tried the FlexComponents list also hosted on Yahoo (lead by Ted Patrick) ? most component gurus are there.
