Detailed Description
The Signal Graph widget is used to plot CDPSignals in real-time.
Modes
It has two different plotting modes: wrapping and scrolling.
Wrapping mode has steady x-axis where data is changing along with updated beam. The beam indicates current time, while in pause it shows the time the graph was paused.
Scrolling mode has moving x-axis on the graph where current time is always on the right side of the plotting area.
Configuring
CdpSignals is the property which can be used to configure which CDPSignals to plot. Insert full signal routing here. Alias text (that will be shown instead of full routing in graph legend) can be concatenated to routing after equal (=) sign (like comp.signal.value=Alias).
