Hi Paul,

I don't see that error. It looks like it must come from
...../lib/Demeter/templates/plot/gnuplot/marker.tmpl

(which gets installed to
/opt/local/lib/perl5/site_perl/5.24/darwin-thread-multi-2level/Demeter/templates/plot/gnuplot/marker.tmpl

for me with Macports).   This file eads::

##--------

{ # -*- ifm -*-
# template for inserting a marker
#   {$x} and {$y} are supplied by the caller and are the points at which to draw a marker
#   {$P->parameter} returns the value of a Plot parameter   {$P->markercolor} '\{/*1.5 \244\}'
}
set label '\{/Symbol \\{$C->default(qw(gnuplot markersymbol))}\}' at {$x},{$y} center front textcolor ls 12
replot

##--------

Maybe try adding a space before "set" just in case something is getting parsed weirdly?

Hi All,
I have installed demeter using Macports on 10.12.1 and while hephaestus seems to run normally, athena has some trouble with graphics. The usual athena perl based panel shows up just fine, but upon loading some data, there is always an error when gnuplot is invoked to plot graphics (as reproduced below). It would seem that the command “set” is missing the first letter. Does anyone have a suggestion as to what to check to fix this?

Axion:perl5.24 $ use_macports.sh athena

gnuplot> et label '{/Symbol \305}' at 400.79999,853.0387 center front textcolor ls 12
^
line 0: invalid command
