[ncl-talk] Possible label bar bug in streamline scalar plots

[Will Hobbs]

Hi Mary

Thanks for your response, that fix works.

Just for clarification to anyone else reading, I got a bit confused initially; the resource gsnOldLabelBar = False needs to be set AS WELL AS lbLabelBarOn = False (otherwise a label bar I still plotted).

​Hil Will,

You are right, this is a problem and I was able to make an existing test fail by setting this.​

There's a weird work-around, and that is to set:

  res at gsnOldLabelBar = False

​This is a hidden resource that is used to switch between two methods for creating a labelbar.  It's code we are testing out, but we are not ready to make public yet. This resource is one that will allow users to switch between the two methods of creating the labelbar, should we ever decide to go ahead with it.

I have already fixed this for 6.5.0, so you will be able to remove the work-around then.

Thanks for the report.

Hi

When I make a streamline plot using the function gsn_csm_streamline_scalar_map_polar() with the lbLabelBarOn resource set to False, I get the following error:

fatal:Variable (lbar_zone) is undefined
fatal:["Execute.c":8640]:Execute: Error occurred at or near line 12166 in file /usr/local/ncl-6.4.0/lib/ncarg/nclscripts/csm/gsn_csm.ncl

I had a quick look at the gsn_csm.ncl code, it looks like there’s a series of ‘if’ statements regarding label bar settings, which are not avoided even though the variable ‘lbar_on’ is False.

The script I’m running reads a LOT of datafiles so I’m hesitant to send it through with all dependencies, but if I’m right it should be easy replicate with any data
