Dear NCL users:
I encountered a weird scaling problem with Y axis when trying to
do a vector (longitude height) plot. The trouble seems to be linked
to the vfYarray, as when I use this resource to label my Y axis,
a large scaling of the Y axis occurs and my plotted wind vectors
are squished down incorrectly. I attached my script below. Has
anyone had a Y axis scaling problem when doing a vector plot
using vfYArray ?
Thank you,
Matt
