[Octave-bug-tracker] [bug #60621] unclear error message in case of missing final semicolon in 'plot' command argument

[Nicholas Jankowski]

Follow-up Comment #1, bug #60621 (project octave):

so that format is supposed to designate a name for the plot. 

looking in __pltopt__.m that parses the plot codes, line 197 starts the part
that should look for the second ; and produce an error:

error ("%s: unfinished key label", caller);

but only if err_on_invalid is set. that doesn't get set, so it sets 'default
plot options', issues a return, and then calls:

 error ("%s: properties must appear followed by a value", caller);

instead.

the err_on_invalid flag is set in the call to __pltopt__, and it's set as
false.  so I don't see how that error could ever get issued.  

hmmm...
