gretl graphs on Linux
by Allin Cottrell
Sorry, I thought I'd sent this message to the list, but I guess I
only sent it to Cri Rigamonti. For the record, I'll post it here,
since the fonts-in-graphs problem on Linux seems quite widespread,
and we have a solution here.

For the benefit of gretl users on Linux who have never seen this fabled
dialog entry, I'm attaching a PNG screenshot!

Thanks very much for trying this experiment. It confirms what I suspected,
namely that the Debian installation of gnuplot does not support the use of
TrueType fonts without special efforts.

OK, we are in business! For the cognoscenti, the recipe is this:
#!/bin/sh
FDIR=$(dirname `locate Vera.ttf | tail -1`)
export GDFONTPATH=$FDIR
to be executed prior to running gretl. Now we just have to figure
out how to make this user-friendly!

gretl-gnuplot bug?
by Cristian Rigamonti
Hi list, I've noticed that putting Italian accented characters into the
labels of a gnuplot graph results in those characters not correctly displayed.
Some notes:
- I'm using iso-8859-1 as the default locale, and everything else in gretl WRT
localisation is working perfectly.
- The problem occurs both with user input strings and with strings generated by
the program (although I've checked them and the accented characters are OK in
the it.po file)
- If I save the gnuplot script for a graph, the script contains the correct
accented characters, and if I execute the script from within gnuplot, the
resulting graph contains correct accented characters
- I'm running gretl 1.5.0 and gnuplot 4.0 (both from Debian GNU/Linux packages)
As far as I can understand, it's like if gretl is failing to pass the "set
encoding iso_8859_1" command to gnuplot (but I might be wrong...).
Is anyone else having similar problems? Let me know if I can do any other useful
tests to track the bug (if it's a bug).

eqnprint after tsls estimation
by Marcin Błażejowski
Hello,
the problem is, that after tsls estimation I can write LaTeX table
output by 'tableprint' command, but somehow I can't run 'eqnprint'
command (I got message, that this command is not available for that
estimator);
is it really impossible to write tsls results in LaTeX equation format?

saved EMF graphs imported into Word BUT...
by John Paravantis
Allin,
I confirm that when importing an EMF graph into Word the margins are ok.
UNFORTUNATELY no matter if I elect to save the graph as a MONOCHROME
metafile, it is always saved as COLOR!

Hello,
I've exact (almost) the same problem, but with polish diacritics
(latin2) and I'm using Debian too (testing mixed with unstable);
the only difference is that I use GRETL compiled by myself (the newest
cvs code)

EMF graphs on Windows
by Allin Cottrell
John Paravantis noted lately that when you paste an EMF generated by
gretl into MS Word, you typically (always?) get a big margin to the
top and right of the actual graph, which then needs cropping if the
inserted graph is to look right.
I've investigated some more, and I believe this is a problem with
the interaction of Word and the Windows clipboard. If you save the
same graph to File as EMF, then do Insert/Picture/from file, in
MS Word, the graph comes out just fine with no excess borders.
I would be interested to hear what happens if you try pasting the
graph from the clipboard into OpenOffice.org on Windows. I suspect
it may be handled correctly.
Bugs in the Windows clipboard/Office connection are not unheard of.
Until recently (Office 2003? not sure) if you simply Edit/Paste'd an
EMF into Word, by default it went in as an old-style Windows
Metafile (wrong, looks bad), BUT if you did Edit/Paste Special...,
then the option that appeared as the default was to paste as an
Enhanced Metafile (right, looks good). Go figure. That's why you
get a little message box from gretl recommending use of Paste
Special.

crash in German windows snapshot
by Sven Schreiber
Hi, I'm getting reproducible crashes of the latest snapshot on windows
whenever I try to open the Data menu.
However, this only happens with the German translation loaded, so I
suppose it could be my fault as the current German translator ;-)
I could need some help investigating the causes though...
Any advice is appreciated,

EWMA parameter estimation in gretl
by Seung Hun Han
i have some questions about EWMA.
How do i using EWMA or SMA method in gretl.
and if i use the gretl by EWMA method, how do i forecast EWMA parameter
lambda..
and what is the best estimator the minimum MSE or Maximum MLE method.
RiskMetric recommends lambda=0.94 in daily obs and lambda=0.97 in monthly
obs....
is it correct?
