Yes it is possible to bisect down to fio release that makes a problem.
Thank you

on version fio-2.13-1.25.x86_64 I found following bug:
when fio is executed with options to write to files (etc : --write_iops_log,
--write_bw_log, --write_lat_log) it creates files with wrong value for one
of the coordinates. So creating the graphs by gnuplot is not possible.
file context example:
341692, 0, 1, 1048576
342510, 0, 1, 1048576
343728, 0, 1, 1048576
344551, 0, 1, 1048576
In old fio version fio-2.8-1.34.x86_64 was everything fine:
339208, 86, 1, 1048576
340561, 26, 1, 1048576
341692, 54, 1, 1048576
342510, 72, 1, 1048576
Could you include a minimal job file that reproduced the problem?
Further do you think it's possible to bisect down to the fio release
that introduced the issue?
