You need to create the figure outside of the camera and pass it in. There's an example here:

JohnCheers,Hi All,Just wondering if there is a way to annotate a volume render with scale lines, text etc? From (quickly) looking at the source it looks like the annotate function only adds a colorbar and doesn't have the flexibility to add other labels?
