the active that is scaled.
To toggle data without opening the menu: hold , press , and release both
keys.
Create Calculation from Linear Fit This option appears in the Tools menu
when the Linear Fit (see page 19) is turned on. Select this option to automatically
create an equation in the calculator based on the slope and y-intercept of the cur-
rently display best-fit line. If the equation of the best fit line is ,
where m is the slope and b is the y-intercept, then the calculation will take the
form . This calculation will appear in the Calculator and in
data source menus with the name “Linear Fit Cal.” For instructions on working
with calculations, see page 41.

to control the appearance of the Graph, make
it emulate an oscilloscope, make it plot two data sets simultaneously, manage
multiple pages, and print.
Data Cursor Select this option to turn on or off the Data Cursor and Coordi-
nates displayed on the Graph. See page 16 for more information.
Connected Lines Select this option from the Graphs menu to turn on or off the
lines connecting the data points.
Graph with connected lines (left) and without connected lines (right)
Scope Mode Select Scope mode from the Graphs menu to make the GLX emu-
late a digital storage oscilloscope. In this mode, the GLX collects and displays
data in repeated bursts. The length of the burst and the sample rate are deter-
mined by the time scale of the Graph display. Scope mode can be used with any
sensor to collect bursts of data; it is especially useful with the GLX’s built-in
sound sensor (see page 58) or voltage sensor.
When you turn on Scope mode, the Graph automatically sets its time range to
30 milliseconds and turns on the Trigger.

It also adjusts the sampling rate of the
displayed sensor so that it will collect about 500 data points (or as many as possi-
ble) in each burst. If you change the Graph’s time scale,

the GLX automatically
adjusts the sampling rate.
