In
the Options menu click on Data Cursor. This will turn the data cursor
on/off.
OR
Click
the left mouse button anywhere in the bottom
annotation line.
If the data cursor is off, this will turn it on at the point coincident
with the mouse pointer. If the data cursor is on, a deliberate click of
the left mouse button in the bottom annotation line at the point horizontally
coincident with the data cursor turns it off. Note when attempting to
toggle the cursor on and off quickly, clicking the left mouse button twice
in rapid succession (double-clicking) produces a much different result
than turning the cursor on and off. See the following function for more
details on double-clicking in the bottom annotation line.
Choose
Options Data Cursor (ALT, O, C).
This will
turn the data cursor on/off.
