<div dir="ltr">Thanks Rick! Hmm, that is interesting. Could it be that I used an array of reference lines? This would make some sense as the previous NCL version I used was 6.5 and didn't upgrade the newer version until last year.

First, go back to your original code without my previous suggestion of reversing the axes. That was based on a wrong assumption.</div><div><br></div><div>1. I do not understand the purpose of "tolong" here. Data type "long" is normally used only for special purposes in NCL, and there is a chance it is causing trouble. Also, "tolong" would reduce plot accuracy by integer truncation. Try simply removing "tolong", and use temperature_top(i,0:23) directly in the function call. Tofloat, todouble, or toint would be safer alternatives if a conversion function is really needed. If you really want integer rounding here, then you should use the round function to reduce roundoff error.</div><div><br></div><div>2. Try completely isolating the plot function from the rest of the program. Write the X and Y arrays to a small Netcdf file. Print (res) and manually recode the printed results into new NCL code lines in a small new test program. Omit all "res" attributes that are not relevant for this plot type. Read the Netcdf file, then call open_wks and gsn_csm_xy, and see if the problem remains. This way, at least you end up with a small reproducer and small data that you can send to the mailing list.
