Re: [Gretl-users] Cannot Find Font Arial
Hi, I tried what Mr. Lucchetti suggested and sure enough it worked, and
I did see a graph from gnuplot. So that means the problem must have been
with the version of gnuplot in debian unstable.
I downgraded all gretl and gnuplot packages to testing and this fixed
the problem and I was able to see my time series graph.
Then what I did was upgrade my gretl version to the version in unstable
which is Gretl 1.8.0-4, but pinned my gnuplot packages (gnuplot,
gnuplot-x11, gnuplot-nox) to the versions in testing, which is 4.2.4-4.
This worked and time series graphs were fine.
So the problem seems to be in one of the gnuplot packages in unstable
which is version 4.2.5-1. Or something else I don't know.
Thanks for your help, I should have tried downgrading in the first
place, but I thought for sure I used gretl after the most recent
upgrade, but I guess I didn't or I didn't do any plots, or I didn't
notice an upgrade to gnuplot.
thanks again,
PJ

I'm running debian testing here, and I'm having no problems like the
one you describe. However, this smells more like a gnuplot issue than
anything else. Try this:
1) open gretl and try a time-series graph
2) you should have in your $HOME/.gretl/ subdir a file called
gpttmp.<something>; that's a temporary gnuplot file we use for
building the png file that is what you have displayed on screen (or
SHOULD have displayed on screen)
3) copy that file somewhere else (say, $HOME/foo.gp)
4) open it with a text editor and remove (or comment) the first two lines
5) try gnuplot on that directly from the command line; that is, do
"gnuplot -persist ~/foo.gp"
If the plot appears, the problem is that for some reason your version
of gnuplot has problems with generating png files. Like I said, I'm
running testing and I've got gnuplot 4.2.4 here, but it appears
unstable has 4.2.5.
Granted, it's just a shot in the dark, but you never know.
