Trend
A Trend is a plot composed of a series of parameter measurements in the order the measurements
were taken. The vertical units are those of the source parameter, the horizontal unit is measurement
number. The Trend contains a single value for each measurement. Trends are especially useful for
visualizing the history of a parameter over an extended period of time or over multiple acquisitions.
1. Open the parameter setup (P
x
) dialog for the measurement you wish to histogram.
A quick way to do this is to touch the measurement table cell.
2. Touch the
Trend button
at the bottom of the Px dialog and choose the function location (
F
x
) in
which to display the plot. The Trend opens in a new grid along with its function descriptor box.
3. Touch the new
Trend descriptor box
to display the F
x
dialog, then open the
Trend subdialog
.
4. Choose a computation
Mode
of All (plots multiple points per acquisition) or Average (plots one
point per acquisition). Enter the number of measured
Values to Trend
.
5. To rescale the Trend, uncheck
Auto Find Scale
and enter the new
Center
and
Height/div
values.
You can also use
Find Scale
to automatically find suitable values.
