This is a great app! thanks for making it available free of charge!
I am a bit puzzled by the scale of things. There is no indication of time-scale (I assume it is in seconds, but my data is in minutes). How does the app know what scale my y-axis has? In my case it’s temperature (deg C) and percent of the gas-valve that provides heat to the proces, but I cannot specify that. Won’t that influence the scale of my gain and Ti?
