In normal mode, one data set is displayed at a time. See “Two Runs” on
page 24 for instructions on displaying two runs simultaneously.
The next-to-last option in the run number menu is Delete Run, which deletes the
currently displayed run. That run will be deleted from all measurements, not just
the one displayed in the Graph.
The last option in the run number menu is Rename Run. By default, data runs are
names “Run #1,” “Run #2,” etc. When you select Rename Run, the GLX
prompts you for a new run name. Enter the new name using multipress text entry
(or an attached keyboard) and press
to accept the change (or press to
cancel the change). The new name will be applied to that run from all measure-
ments, not just the one displayed in the Graph.
For more information on multipress text entry, see page 90.
Data Cursor and Coordinates
The circle around one of the data points is the Data Cursor. Use the arrow keys to
move the Data Cursor; the left and right arrow keys step the Data Cursor to adja-
cent data points, the up and down arrow keys make the cursor jump to the first
and last visible data points. Press and hold the left and right arrow keys to move
the cursor quickly.
The coordinate pair near the top of the Graph indicates the “X” and “Y” values of
the Data Cursor.
If you have a mouse, you can move the Data Cursor by dragging it: click
on the Data Cursor, hold down the mouse button, and move the mouse left and
right to move the Data Cursor along the data plot.
