[ncl-talk] fatal:Variable (lbar_zone) is undefined

[Ismail SEZEN]

Dear Adam, thank you for your kind respond. 

Let me clarify a thing. I already solved my all problems in one way or another, used NCL (thanks to all team members) and now I’m done with it. I’m not in a hurry for a rush. I’m using NCL only for 2 weeks and I tought that I found a bug and wanted to report it and give a hand to community. This is *ONLY* the reason why I’m here. (To help USA users, non-USA users, even to Dennis)

I've been working very hard (night and day) for the past week and I didn’t know what the day is weekend or weekday, I even didn’t know the what time was :). That’s why, please, don’t take personal the insistent second email. I’ve been in e-mail lists for years and I know how things work except sending bug report. Usually, there is a project tracking page and bugs are reported over there. That’s why I was not sure if this list is monitored by the team or not.

To turn on a single labelbar for the panel plot you need to set gsnPanelLabelBar to True in your panel resource list. Finally, to orient the labelbar vertically you need to set lbOrientation = "vertical" in your panel resource list.

The instructions above are exactly what I did.

I already surf the websites. Thanks.

This is not exaclty happening in my situation. But I got the error below. That’s why I dig the gsn_csm.ncl file through the error.

Let me modify your example (thanks again). Please see the attached ncl file.
Also required nc file can be downloaded here https://www.dropbox.com/s/cqu0lr3jautr0u1/wrfout_d02_2015-09-06_00_00_00?dl=0
NC file is big, likely a wrf output file that you have will also work. Not sure.

Thanks.
