<br>
I am trying to make height cross-sections with WRF output using the point A-to-B method, but when I use the order in the function documentation for the "plane" array (xstart, xend, ystart, yend), the results do not match up with the domain. I switched it around to (xstart, ystart , xend, yend) and the results seem to match up. Is the latter the correct order?<br>
