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

normplot  works in 6.3.0.  But error messages were given in 7.1.0.

>> figure; normplot([1:20])

error: plot: properties must appear followed by a value
error: called from
    _plt_ at line 97 column 13
    plot at line 235 column 10
    normplot at line 53 column 5

>> which normplot

'normplot' is a function from the file C:\Octave\Octave-7.1.0\mingw64\share\octave\packages\statistics-1
