I wish to use a vertical cursor line to mark a given point in
time on a series of graphs. I wish to be able to drag the
vertical line across the graphs at will, rather in the manner
of using the grips for sizing sub-windows. However, the
vertical line moves across the image non-destructively and has
nothing to do with sizing. I have mentioned the phrase
"cross-hair cursor" because this is what Tektronix call their
screen cursor. It is not to be confused with the mouse cursor,
which tracks the mouse and does not fully cover the screen or in
X windows, the (sub-)window. However, I want to be able to use the
mouse to position my vertical cursor line and leave it at some
given place.

I will be very grateful for any pointers, code, etc.
