You could use the DrawingTools crosshairs to select and copy points off a
If you want to write your own dynamic presentation, you could create your
own locator by writing a Graphics statement as the second argument to the
Locator statement. With your copy of Presentations you could use the
CirclePointLocator statement to create a better looking and smaller locator.
It is contained in the PlaneGeometry section and there is also a
step-by-step tutorial on constructing custom dynamic presentations. You
could display the underlying graphics and then have a point locator that
simultaneously displayed computed values from its location.
The WRI militaristic gun-sight locator isn't the best looking and the cross
hairs don't seem to be perfectly centered anyway, so I would do away with
them but in any case you can always define your own locator. One other point
is that the ImageSize of the locator graphic determines the cursor "capture
area" for the locator.

I use Locator to pick up some points of the graph originated form
experiment. In this case I would like to slightly modify the Locator
appearance, since the gray ring on its background sometimes prevents me
from seeing the point I want to pick up. I would like to leave its cross
structure as it is at present, but to remove the gray ring. As an
alternative, the inned (and may be, the outer) diameter of the gray ring
could be increased.
Do you have any idea of how to do this?
