Lady Heather v6.05 defaults to three plots for my trueposition GPSDO: temperature, # of satellites, and EVAL. What is EVAL? It's a dimensionless quantity, so no hints. The LH manual doesn't mention it. (Plot type 8 was reserved for future use, so maybe this is new in the beta?)
I'm also wondering if there is a way to tell which features of the program are supported on a given device. E.g. when I try to plot PPS or OSC data, I get a flat line, so, presumably not supported?
