[Gretl-users] Cannot Find Font Arial

[Paul Jones]

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
