Artur & Sven,
Thanks for your help! I'm using the Penn World Tables. Gretl correctly recognized it
as a panel, but I hadn't set the dataset structure. When I did that, it
worked...almost. Running the attached script, the first plot still has observation
numbers, but the rest correctly show the year.
On the gretl web page I'm only seeing various relatively outdated
version of the PWT (probably they should be updated...), apart from the
fact that they don't seem to be in a formal panel structure. So how did
you get or make your gretl datafile?
thanks

You can d/l PWT 10.01 in dta format from
https://www.rug.nl/ggdc/productivity/pwt/ and open it in gretl.

I downloaded version 10 from the U. of Groningen:
https://www.rug.nl/ggdc/productivity/pwt/?lang=en,
then imported it from Excel.

OK, but maybe then we should make the converted (gdt/gdtb) dataset
available more directly in gretl.
- On https://gretl.sourceforge.net/gretl_data.html there is a subsection
"Penn World Table" which talks about the incarnation 56 (5.6), quite
outdated. (Actually, I wonder if the section "Big datafiles" is needed
20 years later, in the sense that the meaning of "big" has shifted in
the meantime.)
- Then there's the page "online gretl databases"
(https://gretl.sourceforge.net/cgi-bin/gretldata.cgi?opt=SHOW_DBS) which
has pwt61, pstna and pwtna62. The latest given date there is the year
2008, almost as outdated. I guess this is the same thing that you see
from within gretl via File / Databases / on database server. Basically
the only databases that seem to have been updated recently are the ones
from the FED (fedbog and festl, in 2022).
Any downside to including the lastest PWT in there?
Why actually are the ECB's AWM datasets located in the sample datasets
collection instead of the databases? They're not textbook-style
illustration data. Or am I misunderstanding the rules that determine
where a dataset/database is to be found in gretl? Even after all these
years I find it quite confusing, actually.

I'll pick one of Sven's points for now...

* If a data collection contains series of different frequencies then
(leaving aside the special case of MIDAS files) it must be packaged as
a gretl database.
* It may also be preferable (more parsimonious) to use the gretl
database format if a collection contains series with substantially
different observation ranges. In a regular gretl datafile all series
must be of a common length (padded with NAs if need be).
* There's a certain presumption in favour of a database for very large
collections of series.
That leaves some room for discretion. I guess we could go either way
with the AWM files but they're quite compact so using regular datafile
format seems OK. The supplied datafiles under the "gretl" heading are
mostly not textbook-oriented.
