[ncl-talk] A error plotting markers

[Mary Haley]

The word "marker" is arbitrary. The unique_string function will take
whatever string you input to the function, and return "xxxxxN" where
"xxxxx" is the string you entered, and N is a unique number counter. I just
used "marker" because I thought you were calling gsn_add_polymarker, so it
was somewhat meaningful to use the word "marker". But, it's basically a
dummy variable, so you can call it whatever you want.

BTW, you can usually google an error message and hopefully you'll get a
useful hit.  I googled "no contour data" and it came up with this link:

I then clicked on "next in thread" so I could see the answer:

https://www.ncl.ucar.edu/Support/talk_archives/2012/1762.html

which is:

 Try setting cnNoDataLabelOn to False.
