[Radiance-general] Where does bgraph look for .plt files?

Tue Apr 15 11:49:56 PDT 2014

I very much appreciate your efforts Sir. Everything on my system seems the
same as you wrote.

csh -f -c 'ls -l ${MDIR}line.plt'
-rw-r--r-- 1 root root 728 Jan 25  2012 /usr/share/radiance/meta/line.plt

/usr/share/radiance/meta/line.plt file's first few line are:
#
#       This file defines a standard line plot,
#       where a curve is represented by lines
#       connecting each point.
#

include = standard.plt          # standard definitions

lthick = 2      # line thickness

#
# Curve defaults:
#

Athick = lthick                 # line thickness for A
Alintype = 1                    # line type for A
Asymsize = 0                    # symbol radius for A
Acolor = 4                      # color for A

Thank you.
