[Octave-bug-tracker] [bug #62394] Normplot error message

[Nicholas Jankowski]

Follow-up Comment #1, bug #62394 (project octave):

haven't stepped through, but looking at the source for normplot, the last
change was in 2017
(https://sourceforge.net/p/octave/statistics/ci/427b93d66b774b7da542ef699738096e04d362ff/log/?path=/inst/normplot.m)
so it appears the change must be due to a change in ___plt___.m, plot.m, or
maybe ___pltopt___.m  which is called right before the error. 

since that's the 'ischar...' section, it must be dealing with the last
parameter supplied by normplot, '[num2str(i),";;"]'.  Which for your normplot
example with only 1 plot is "1;;".  Need to look a little further to see why
it sets off the "if (nargs == 0)" condition on line 96 when it didn't in
v6.4.0
