I think that any specialized industry or field will have some
specialized ways of graphically representing their data and that leads
to XControl use. These controls and indicators have been developed to show something the way that is most appropriate for the application. Recently (in the last decade or so), people have begun to replace these with digital displays that the users don't really care for. XControls allow the creation of a specific control that better minimcs the original analog control/indicator.
There are a number of gages used in industry that have a latency (they lag the actual data). Including the logic of the delay in the control would be a decent use.
Aircraft indicators for example: Attitude and altitude would both be useful.
Smith charts could be an example. The way LabVIEW has done them for years has been a bit awkward and now they can be done better.
You could create a picture control that would look like a transmission shift pattern and merely output the gear number; hiding all of the drawing/dragging code in the XControl.
Creation of military style safety switches (where you have to flip up a cover to then switch the switch, closing the cover or turning off the switch both shut it off).
Anything that has lots of configuration could hide all of the configuration in the XControl and access it through the pop-up menus, drag and drop, special location double clicks, etc.
Just some thoughts, but I haven't had my coffee yet!
