The following definitions are used to explain creating and using graph plots.

TermDefinition
Active channelA channel that is either selected or pinned
ChannelA stream of data that can be added to a graph plot
Channel cacheThe amount of channel data stored either in memory or disk. The Cache Memory Limit (see Preferences parameters in the Vicon Evoke Reference Guide) controls the threshold when data is to be written to disk.
Channel source

A selection that provides one or more data channels and includes:

  • Vicon camera
  • Object, marker, or unlabeled reconstruction
  • Character or segment (solving skeleton or retargeting skeleton)
Channel type

A channel source may provide multiple data streams of different types, which may be selected from the dropdown menu on the Graph Plots toolbar

ComponentOne part of a channel data value
Dependent channelA channel that is only available with a channel source selected (eg, object position)
Frame numberA number that increments sequentially for each frame of system data received
GapA time period of missing channel data (eg, because tracking was interrupted)
Independent channelA channel that is available without a channel source being selected (eg, DataStream Output Latency)
Live modeA mode that displays data from the connected live system
PinningThis locks a channel on a graph plot even if the channel source is de-selected
Review modeA mode that displays data from the selected review clip
SampleA set of channel component values, taken at a single point in time
Sample numberA number that increments sequentially for each channel sample received. Channels are sampled at the system frame rate, so the sample number is equal to the frame number.
SubplotA subdivision of the graph plot containing one or more traces of the same type
TraceThe visual representation of a single component of a channel data stream on the graph plot
