Hi…  
Either as an addition to or replacement of the existing colorization depiction of pressure, would love to see isobar lines. Just more visually telling of fronts or wind events.

Hi @ohaness1,

Isobars are very hard to do with the swiping action. They are too costly to compute on the fly. I’ve been thinking of way to do this or pre-compute them - it’s not easy. There might be some tricks in OpenGL to do this but I haven’t tried them yet.

In my upcoming release, you can turn on pressure with stepped color which indicates these isobars.

Cheers, Duane.
