[Gretl-users] gnuplot command

[a b]

Hi everybody !

On undated data, I try to draw a scatterplot by the
following :
"scatter1" <- gnuplot x y
"scater1".show
but I get two message error (attached) and a black
graph window on the screen .
I tried with other data --annual and undated-- and had
no problem!

Best,
Artur

What's the build date of the gretl version you're using (see under
/Help/About)?

I can't replicate the problem here -- could you maybe send me a
copy of the data file for which you're drawing the plot?

I'm attaching the data file and the script file.

Thanks. I see what the problem is: it's the "display name" of the
y variable, namely "Quantit? d'engrais". The embedded "'" causes
trouble when gretl writes (for gnuplot):

set title 'Quantit? d'engrais... '

So far as gnuplot is concerned, the title ends at "d'", leaving
"engrais" hanging there as a syntax error.

I'll fix this, and also another related thing: I now realize that
the GUI mechanism for changing the display name involves using the
"label" alias for "setinfo", which I just deleted!

I'll fix this,

Does this mean I can write "Gau?'sche" in the German translation again? ;-)

Or to put it more seriously: what is the limitation of gnuplot in terms
of characters?

cheers,

Yes, that should work now.

Single quotes or apostrophes are now OK, double quotes are not OK.

Gnuplot doesn't do proper i18n so handling the encoding/recoding
when interfacing with gnuplot is a bit of a nightmare. I've
patched up a few things today, but I can't guarantee that things
will work with the full generality that one would like.

Allin.

I'm afraid it doesn't yet ! At least for the "Quantit? d'engrais" label ! I have the same trouble !
By the way, when Gretl automatically computes/ transforms variables --such as log, squared and so on -- it adds a description; Could be possible to set the display name as well ?

Have a good weekend !
Best regards
Artur
