    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?

    Hi, all time must be in seconds, always. The scale of the axis must the exact same that is used to feed in and read out of the PID block that will be used in your process loop.
