@Jeremy
My interpretation of you reply is you recommend snippets of code
shared here should be both complete as in «all the relevant
instructions to demonstrate the issue» .and. self sufficient for a
test run, i.e. to include a minimal set of data to process.  In other
words, to include gnuplot's datablocks (`$data`) as in e.g.,

```gnuplot script
$data << EOD
1 2
2 4.5
3 3
4 -1.2
5 0
EOD

set terminal pngcairo
set output "test.png"
set grid
plot "$data" w lp pt 2 lc "blue" title "par example"
```

or, considering only a dozen of records of Emanuel's log

```gnuplot script
$data << EOD

@moderators of the mailing list
Perhaps the suggest to include small datablocks to render MWE easier
to replicate could be included in one of the mails when subscribing to
the list.
