Apparently gretl has a short limit on string length

So part of my ylabel string (which I was setting with setinfo)
is not being passed to gnuplot. That explains the clipping on
the right. Can you provide a longer string?
But I still sometimes lose a one (?) pixel band
at the very left of the label.
I've checked that the pixels are really missing (that
it's not just a screen resolution issue) by saving the
file as PNG and resizing it. They are missing.
It is also not a font problem bc it happens only at
the beginning of the label. (E.g., I can get rid
of it by adding a space.)
Here is the more puzzling thing. Suppose I see this problem
(missing pixels) in a graph I have saved as a graph obejct.
Now I go to the icon view, pick Edit Plot Commands, and
without changing anything, I run the commands: I do not
see the problem!
This is on Windows? The drivers are different in the two cases.
The cairo-based driver is used for gretl's PNG plots, but if you
send the plot commands to gnuplot that will be using the Windows
GDI driver. So if it's a gnuplot problem it looks like it's the

of gnuplot that comes with gretl?)
Yes, I think so.
Finally, I uncovered what I consider a bug. (?) If I use
setinfo to set a name, it is used as my ylabel, **even if**
I explicitly set a ylabel. This violates the specificity
principle, which should give priority to the most specific
request (the ylabel I set in a specific graph).
I'd agree that sounds like a bug. Are you setting the ylabel via
the GUI, or via extra commands passed to gretl's "gnuplot"
