Trace settings

There are four independent Traces, which all use the same data from each scan. They can be made visible or hidden using the tickboxes and each can be set to normal, average, max or min hold. Trace averaging is controlled by the slider to the right of the 'Start frequency' box and can be set to average between 1 (no averaging) and up to 100 scans.

Each trace has 1 marker associated with it. Because the traces are always active, even when not visible, all 4 markers can be used on one trace if all the others are 'turned off' and set to the same processing type (normal, average, max or min hold).

The max and min hold is performed over a limited number of scan samples, so will eventually decay. (Future fix).
