Typically you would use Two Measurements mode to display data from two
different sources, but you can also use it to display two runs from the same
source. Select the same source from both data source fields, and different
runs from each run number field. For another way to display two runs from
the same source, see “Two Runs” below.
Two Runs Select Two Runs from the Graphs menu to display two data sets
from a single data source.
In this mode, a second run appears on the Graph. A second run number field
appears in the upper right corner (below the first run number), which you can
select to choose a different run.
One of the runs is plotted in black, and the other one in gray. The run in black is
the active data. To switch activity to the other run, hold
and press . The
Data Cursor appears on the active data. If you select a tool from the Tools menu,
it is applied to the active data set.
Both runs share a single pair of axes and they are scaled and moved together.
If you are using a mouse, you can switch activity to a run by clicking on
the line above its run number.
Two Graphs Select Two Graphs from the Graphs menu to display two separate
graphs simultaneously. This mode is similar to Two Measurements mode (see
page 23), but each measurement is plotted on the top or bottom half of the screen,
rather than overlapping.
One of the measurements is plotted in black, and the other one in gray. The mea-
surement in black is the active data. To switch activity to the other measurement,
hold
and press .
The Data Cursor appears on the active data. If you select a tool from the Tools
menu, it is applied to the active data. If you press
to scale or move verti-
cally, only the active data will change. However, moving the Graph horizontally
or changing the horizontal scale will affect both sets.
If you are using a mouse, you can switch activity to a measurement by
clicking on it.
New Graph Page The GLX supports an unlimited number of graph pages.
Select New Graph Page from the Graphs menu to configure a new graph while
preserving the previous one.
When two or more graph pages exist, each page appears in the Graphs menu. To
make a page visible, select it from the menu.
If added graph pages make the Graphs menu too long to fit on the screen, an
arrow or arrows (
, ) will appear on the right side of the menu to indi-
cate that some of the menu options are not visible.
Press the up or down arrow key multiple times to move the highlight beyond
the visible portion of the menu. The menu will scroll to bring other options into
view.
If you are using a mouse, you can click the arrows to scroll the menu.
