I am trying to plot isobars and isotherms on a surface chart. The data and the fronts plot, but not the isobars/isotherms. Any ideas?

Haven't had time to go in depth but just testing the:
ANALYZE,HILO CONT CINT=4 COLOR=255:000:000 LINE=2 SLPR
ANALYZE,CONT CINT=2 COLOR=000:000:000 DASH=2 TEMP

works fine.

Thanks, Greg. I copied that into my script and nothing showed up. Any ideas?

Here's my script.

Moved some commands around and it worked for me. Try this:

Still no contours. Could there be a setting somewhere that I need to set?

There are not any settings that stand out in my mind. I do use Cressman (under File, Preferences, Analysis).

Also, make sure that there are not any "spaces" at the end of each line. Your cursor should immediately follow the last letter on each line.

HMM...those all look OK.

I don't know what to tell you. Your first script didn't work for me so I changed the commands and they did work (and worked again a few minutes ago).

Thanks anyway. The contours would be black, correct? Wondered if I'm not seeing them because they're conflicting with the background.

Your isobars are black and isotherms are red.
