What are the advantages of a Picture Control over a Graph, if any?
How often are Picture Controls used? For what purpose?

Probably, the most significative advantage is that you can display images and images files (JPEG/PNG/BMP) in LabVIEW at run time (Especially, without the need of IMAQ)

Because of this, I use them extensively.

Tim,

Another big advantage, is that the mouse can be read. This way you can
program LV to select object in your picture, and drag them around, delete
them etc.

And obviouslly, it is much easier to draw (e.g.) a circle in a picture, then
to draw a circle in a graph. (And if you succeed in drawing it, try filling
it with a color! It's doable, but no fun at all...)

Disadvantges are: If you draw data points, you'll have to make your own
scales, autoscaling, 'scrolling' of the date, etc.

How often you use them depends greatly on the field you're in. If you make
games (yes, in LabVIEW), vision, imaq, ..., you'll use pictures. If you're
in DAQ, T&M, research, you might never need them...

Regards,

Wiebe.
