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

[Mary Haley]

​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.

--Mary
