Dear Allin
I'm calculating the Gini index on a very huge dataset.
While in the command line the operation hardly takes a couple of
seconds, through the GUI (Variable -> Gini coeff) it lasts quite long
and gretl crashes with the following message error. Well, maybe that's a
gnuplot issue I guess!
Best,
Artur

It doesn't actually crash, does it? Just fails to display the
Lorenz curve graph? That's fixed in CVS: we down-sample if
there are too many points for gnuplot to handle.

well, it did crash...without displaying the graph!

That's good! With the new CVS
gretl doesn't crash anymore but fails to
show the graph (neither the text window) and produces the same error
message :-[

OK, it didn't crash on Linux.

That's good! With the new CVS gretl doesn't crash anymore but fails to

message :-[
The update was only in the CVS code repository, not in the
snapshot files -- but the snapshots are now updated.

The update was only in the CVS code repository, not in the
snapshot files
So why did it stop to crash ?!?! Mmmmmm! :-\
-- but the snapshots are now updated.
Anyway, now it works
perfectly and very fast: it takes some 6 seconds
for 10 million obs!
Thank you Allin!
Best,

You probably thought about that yourself, but are there other contexts
where gretl could give gnuplot more than it can handle?

Yes, that occurred to me too, but I haven't yet tried to do anything
about it.

And I'd be tempted to add: time is on our side. Even if there were any,
we've been using gnuplot for long enough that I'm confident that they
ought to be pretty unlikely in real life, and probably easily fixable.

I'm not on Windows right now, otherwise I would try to provoke the crash
by simply throwing many many data at gnuplot (from within gretl) to
produce a scatterplot. And if it were possible to replicate the crash, I
would say it should be prevented. But of course you're right, this isn't
terribly important.

Well, I did try with the same XXL dataset which did work
fine for the
Lorenz curve...
And if it were possible to replicate the crash, I
would say it should be prevented.
...and gretl didn't crash although it failed
to show the scatterplot
producing the same gnuplot's error message.
But of course you're right, this isn't

you're right, it isn't! I dont' think that handling
a 10-million obs
dataset is of every day use :)

Besides, if you had a systematic way to provoke a crash in gnuplot, that
would be a gnuplot bug, not a gretl bug. Of course we could (perhaps
should) do all our best to help them fix it, but division of labour is a
good thing.

good point -- but doesn't this then apply to the case of the OP?
