Thanks for clarifying the situation for me. My main use of J is for what's
called Explorative Data Analysis. This means that I construct J-expressions
on the fly, putting data into temporary variables and, quite often, use
plot to get a feel for my data. I.e., my use of plot is not in a carefully

Yes that’s the one thanks Chris. It is very useful for better understanding
complex combinations and I’m sure it would be well worth resurrecting,
preferably with documentation and even a video (@Bob T?)

Raul, I think it is so useful it should be available immediately on starting J!

Brian, I agree with you totally re fgh.ijs, which I consider to be exemplary,
and also about Trace which I find confusing and disappointing.

Well done Rob, that’s very nice indeed!
(As others have pointed out the one I was referring to was called fgh.ijs which
may have disappeared in the sands of time!)

Could you write a short verb to validate the data which calls plot if the
data is correct to plot or give you an error message if not?

Re "a short verb to validate the data"
How does a *short* verb determine that all possible combinations of plot
instructions are correct? try. doesn't work. And why doesn't plot do it for
me?
try. 3+3

Consider the following (which I generated in the browser base
Perhaps it could supply the plot parameters you put for your normal use.
Validate lengths are correct. Not All possible errors, but the ones you
have made often.

Pablo,
If the issue is with jQt, is JHS an option? JHS does not use Qt at all.

The endless loop or crash is a result of jqt popup error message inside
paint loop.
You can workaround it by define
wdinfo_z_=: echo_z_
so that messages won't be popup

First picking up on Don's suggestion: simply replacing 'plot' with ';' as
shown below can show that the number of arguments for plot are
inconsistent. But this may not satisfy your bigger question.
'xlabel a b c d' ; 3 4 5
+--+-+
|xlabel a b c d|3 4 5|
+--+-+

The 4th sample statement in Chris's script doesn't work for me.
