Array signal curves can be plotted online as a single entity, where each array element or 'sub-curve' is referred to as a Trace. Each trace may be enabled or disabled separately (i.e. shown or hidden).
Trace properties and control can be accessed through a special drop down menu with a single left-click on the curve title in the curve legend.
Before adjusting any trace properties, you must first invoke the trace drop-down menu as described above. The drop menu consists of four separate columns, each allow for easy access to certain trace properties. These columns are described below:
Trace: Indicates the trace number and corresponding color setting. The number corresponds to the array index number of the multi-signal curve. To change individual trace color, see Adjusting Curve Properties.
A: Stands for Active. Select the radio button in this column to select the active trace. The active trace will be the default focus when switching to cross-hair mode. Also, only the properties of the active trace may be adjusted: See Adjusting Curve Properties.
V: Stands for View. Left-click the individual check boxes in this column to hide/view individual traces. You can hide/view all traces by left-clicking on the V itself.
B: Stands for Bold. Left-click the individual check boxes in this column to bold/un-bold individual traces. You can bold/un-bold all traces by left-clicking on the B itself.
M: Stands for Mode. This function is only valid when the curve is displayed in a polygraph. Left-click the individual boxes in this column to change the trace mode from digital to analog. When in digital mode, the trace will be displayed in a special two-state format, where the state depends on whether it is above or below a preset Threshold value. For more details on setting threshold and other digital properties see PolyGraphs.
