Another question: Are the events permanently tied to the x-axis values? When I have my X limits set to 50-450 I get this:
Is there a layman's way of getting the events to display with a 150-450 temp range?
Well, a little off topic ...
Events have by default their own axis which are only indicated by those horizontal bars below the first phase mark. If you move the lower limit of the first phase up (within the Phases dialog), those bars will follow. However, there is also an option to have the events aligned by value to the y-axis if the flag "Snap" is ticked in the Events dialog.
