Would it be possible to see a bolder (or different colour) zero degree line on the temperature UI graph? I think quick viewing of temperatures above and/or below 0°c could then be deciphered at a glance. This would be very useful to us gardeners of the world.
In fact, perhaps a better advancement of my idea would be to have a highlighted line(s) that could be dragged/set to any temperature position at the user’s preference?
I’m running android and use metric units.
I’m guessing this could be programmed as a line at freezing and then regardless of temperature scale it would display. Does anyone use Kelvin for meteorological temperatures? 
Indeed… Although not sure about absolute zero! Don’t fancy carrying around a 3ft tall phone! 
But seriously, I think a programmable line would be useful for everyone that decides their own preference from Celsius to Fahrenheit to Kelvin…
“Does anyone use Kelvin for meteorological temperatures?”
Some meteorological parameters are indeed specified in Kelvin (Equivalent Potential Temperature aka Theta-E … Potential Temperature aka Theta … Brightness temperature … to name a few).
Nothing that you can get froma Tempest though.
Great Idea. Very Helpful!
