In all graphical windows, two traces (TRACE A and TRACE B) can be recorded on y-
axes along an x-axis. The "Y-Source" parameter field is used to determine which mea-
surement functions are mapped to the y-axes. For multi-channel analyzer instruments,
the input channel to be mapped can be selected using the "Channel" parameter field.
In the sweep graphics, every trace can also consist of several individual traces (scans).
In many cases, settings are to apply to both traces. The track boxes provide multi-col-
umn panels which allow settings to be transferred from the left-hand to the right-hand
column without the parameters having to be entered a second time.
If the track box is activated, all of the settings within the function group are applicable
to both columns. All fields with applied settings are shown in the right-hand column as
grayed out display fields. These fields cannot be accessed while the track function is
active. If a setting is changed in the associated parameter field in the left-hand column,
this change is also shown in the display field in the right-hand column.
Displayed values
The data which is to be graphically displayed can be determined for each trace. Usu-
ally this data comes from the selected measurement functions; however, saved data
(reference data) can also be displayed.
With Label Auto, the y-axis of the graph can be labeled with the data name selected
under Source (see example below), or users can define their own label.
The "Hold" radio button is used to "freeze" the graphical display.
Additional scans can be added to a graph ("Append"), or existing scans in a graph can
be replaced by new ones ("Replace").
Reference values
The reference value for relative measured values can be set here. This can be a fixed
preset value; however, values measured at a different location or entire scans from
files, from the other measurement channel and so on can also be used automatically
as reference values / reference curves.
