[ncl-talk] gsLineThicknessF (bug?) in NCL 6.5

[Mary Haley]

Hi Nick,

This is definitely a bug. I'll provide a work-around a little later in this
email.

Meanwhile, as a favor, could you submit an issue using NCL's github issue
tracker? We're moving from JIRA to github for issue tracking, and would
like to get our users on this as well.

To report the issue:

[1] Go to the NCL github page:

https://github.com/NCAR/ncl

[2] Click on the "Issues" tab near the top of the page

[3] Click on the green "New Issue" button

[4] Fill in the title and description. The title should be descriptive, but
as brief as possible. What you had for the subject of this email would
work.

When filling out the description, you can use the attached sample script
which illustrates the problem. Unfortunately, github doesn't let you select
files with a ".ncl", but if you rename it to "xxx.ncl.txt" then you can
attach it to the issue.

Or, you can copy the script, and then in the github description box, if you
paste the code surrounded by these two lines:

```ncl
[....paste NCL code here...]
```

Then it will recognize this as an NCL script and will highlight bits of the
code for you!  You can click on the "preview" tab to see what it looks like.

[5] Once the description is done, click on the "Submit new issue" button to
submit it.

Back to the problem at hand. There are a couple of work-arounds.

*Work-around #1*

One is to fix the $NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl script
yourself.  Edit this line:

  gsres_tmp = get_res_eq(res2,"gs")           ; Get resource list for
lines. Remove gsFill

and change "res2" to "res":

  gsres_tmp = get_res_eq(res,"gs")           ; Get resource list for lines.
Remove gsFill

*Work-around #2*

If you don't want to edit and change
$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl directly, then I created
a separate "gsn_table_fix.ncl" script for you, that has the new gsn_table
with the one line fix.  You can include this fixed script in your current
NCL script with:

load "./gsn_table_fix.ncl"

Let me know if this doesn't work for you.
