Rex,
We recently upgraded to version 2.11.0 here at Tallahassee Community
College.
LON-CAPA 2.11.0 requires gnuplot 4.4 or later.
Any thoughts of where to look as to what might be wrong?
You will need access to your server's command line, or ask someone who
has that access to take a look:
Look in /etc/httpd/logs/error_log for lines such as:
"/home/httpd/perl/tmp/abert_tccfl_<UNIXTIME>_<NUM>_plot.data" <error>,
referer: <URL>
where <UNIXTIME> is timestamp (seconds since epoch) e.g., 1408699963
where <NUM> is a numeric ID e.g., 1149728
where <error> is the error message generated by gnuplot
where <URL> is the URL of the resource being displayed.
The command sent to gnuplot will be in:
/home/httpd/perl/tmp/abert_tccfl_<UNIXTIME>_<NUM>_plot.data
and if this was a data plot, then the data will be in:
/home/httpd/perl/tmp/abert_tccfl_<UNIXTIME>_<NUM>_plot.data.0
Other things to try ...
Do you see the same issue when your session is hosted on one of the
MSU servers, e.g., log-in via:
https://s10.lite.msu.edu/adm/login?domain=tccfl
and you display the same resource?

Quoting Rex Abert <abe...@tcc.fl.edu>:
We recently upgraded to version 2.11.0 here at Tallahassee Community
College. Checking through some homework problems, I am unable to
see gnuplot graphs in problems containing them. I see simply the
"ALT" text "dynamically generated plot".
Any thoughts of where to look as to what might be wrong?
