LocatorRegion

LocatorRegion
is an option for Locator that specifies where the locator object should by default be allowed to go when it is dragged.

Details Details

Typical settings include:
Automatic the plot range of the current graphic

Full the full image size of the current graphic
LocatorRegion->Full does not allow a locator object to go into space left as a result of a mismatch between settings for AspectRatio and ImageSize.
LocatorRegion affects only interactive manipulation of locator objects, not resetting through Dynamic.
