thanks! Could you explain, what is exactly the advantage if i use it when changing for example the color of a graph. What happens differently in the two cases?
If you do a lot of changes (eg. change several settings of several plots) it will take considerably longer without defer panel update, because each (!) setting of a property (even if you combine several properties in one node) will lead to an update of the front panel.
Defer Panel Updates makes LV not synchronise UI actions with the screen updates.
Try inserting 200 (or 2000) items to a tree control. It will take forever. Turn Defer Panel Updates on, and it's done in a flash (well, much faster).
Even updating values with a property node makes each "write" synchronise with the screen. So updating a control with a property node 6000 times might take a relative long time (notice the flashing). Try Defer Panel Updates on and off, and see the difference.
You really need an example after all the input you got?
OK, here's a very simple one.
Kudo for your patience. (But he did ask for two VI's...)
Well, he can start it two times with two different settings for the Boolean in the front panel.
