Ok, I have added another keyword:

WIPE - used with a ROI to delete points from a displayed plot. Execute
as follows:

IDL> display, findgen(100), sin(findgen(100)/10.)+randomu(1,100)/5, $
psym=4, linestyle=6, link=-1, name='ONE'

; WIPE will only work if LINK is < 0 - safety feature.
; Now, use mid mouse button to surround a bunch of points in the window.
; Then, type:

IDL> display, /over, /wipe, name='Linked ONE'

and watch the points disappear :-)
Cheers,
Pavel
P.S. The observant ones will of course realize that once I have fitting
ability, it appeared that when I have all points displayed, the fits
looked bad, so WIPE is an easy way to leave only those points in that
produce a "correct" fit. This is of course NOT "massaging" the data :-)
