Hi all,
I am having a problem with the titles of the plots saved as pdf or eps
when variable names include underscores.
It seems like underscores are interpreted as in LaTeX formulas when the
plot is saved as pdf and eps.
Is this a bug? Is there a workaround?
I attach the same plot saved as bmp and pdf and you'll see the difference.
Best,
Matteo

This is due to a change in behavior in gnuplot 5 relative to earlier
versions. Before, an underscore was by default just an underscore
but now "enhanced" mode is the default for titles, labels and so on,
and in that mode underscore produces a subscript.
In gretl's standard PNG output we've turned off enhanced mode to
avoid that problem but it seems we've forgotten to do that for pdf
and eps (?). The trick is to include "noenhanced" in the line
of the gnuplot file that selects the "terminal" (output) type.
I'll look into it.

If I remember correctly, the Latex-type "a\_b" works.

Yes, that's right: that gives you an underscore when gnuplot text is
in "enhanced" mode. The difficulty across gnuplot versions is that if
you do that in gnuplot 4 (by default in non-enhanced mode) you get a
literal backslash-underscore sequence.

It seems like underscores are interpreted as in LaTeX formulas when the plot
is saved as pdf and eps.
This should now be fixed in git and current snapshots.
