Hello
I am a bit lost when using the function-> boxplots (const int *list, const char
*literal, const DATASET *dset, gretlopt opt)
When dset contains data I get the error-> *** error: allocate_Z called with non-NULL Z,
and if dset have no data then I don't know how it would make a boxplot for the data.
Any thoughts on how I would use the C/C++ API to make boxplots?
Thank you

I guess there must be a good reason that there is this warning in
allocate_Z (in lib/src/dataset.c) but OTOH it's not obvious to me that
after printing this message to stderr the rest will fail. So if you
excuse the stupid question: Does it actually fail, or do you just see
that printout?

perfectly fine question, yes it does fail to show the boxplot, and error returned from the
boxplot function is 0.

OK well but 0 is no error, right? The boxplots function in
lib/src/boxplots.c just says it "Constructs a boxplot command file for
use with gnuplot." So in order to get it plotted further action would be
needed I guess, by invoking gnuplot on the produced command file.
Sorry, can't tell you directly how gretl proceeds with that internally
without trying to check myself.

Original code for Box-plots was made by Allin, but later changed to use
gnuplot (I think).
