[ncl-talk] Fwd: error with gsnYRefLine

[Adam Phillips]

Hello,
Thanks for sending along a self-contained script that shows what you are
doing. What version of NCL are you running? I was able to get a bar chart
using your script without an error message. I have attached the plot. The
NCL version that I used was v6.4.0. If you are using a version earlier than
6.4.0 I suggest upgrading to the current version 6.6.2.
