WinDarab has the concept of 'Alias Channels' These are channels that can be 'place holders' for other channels. Common usecases include:

• Renaming channels e.g. nmot -> Engine Speed
• Placeholding missing channels
  • If a channel is missing (removed from logger or not on telemetry) but is used in a Math Function

Potential [source] channels are checked in order from top to bottom. If a potential channel is found and is valid, it is used as the source for the Alias Channel.

• An alias channel name and the names of its possible member channels can contain indexers. WinDarab automatically expands the alias channel definition (internally) to discrete alias channels:
• The indexer can be given as a list of name parts “[part1,part2]” or a range [1..4] or [a-d] or any combination [a,b-d]
• The number of indexers in the alias channel name and its member channel names have to match!

You want alias channels wheelspeed_fl, wheelspeed_fr, …

Now you can create an alias channel definition named “wheelspeed_[fl,fr]”

And give the following member channels:

• vspeed_[fl,fr]
• vwheel_[fl,fr]
• vspeed_[0..1]
