Thanks! I suspected it must've been something with gnuplot because it
seems to work with Ubuntu 15.xx (running Gnuplot 4.xx) and breaks with
Ubuntu 16.xxx (running Gnuplot 5.xx).
I tried contacting Erwan for an answer on a possible update but gotten
no response.

I'm trying generate graphs with logs create by fio using fio2gnu and keep
getting this error when generating graphs for iops or bandwidth:
1 files Selected with pattern '*_iops.log'
|-> 4k.results_iops.log
Running gnuplot Rendering
"/usr/share/fio//math.gpm", line 25: no datablock named $1
"/usr/share/fio//graph2D.gpm", line 25: no datablock named $1
Rendering traces are available in the current directory
Checking the directory listing only shows this file:
$3.png
Am I missing something in fio profile?? Here's a snippet:
This happens because you have gnuplot 5 and it dropped support for the
$1 way of passing arguments on the command line (see
http://stackoverflow.com/a/31815067/4513656 ). To get around this both
the .gpm and and fio2gnuplot would have to be rewritten to use a
different means of passing parameters in. I'm not sure any method
beyond using environment variables would work for both old and new
versions of gnuplot...
CC'ing the original author of fio2gnuplot for comment.
