Follow-up Comment #3, bug #60482 (project octave):
looking through hist some more, apparently hist itself just ignores anything
non-numeric for the purpose of the calculation. if no outputs, it passes
everything else as parameters to bar for plotting. If there are outputs (like
your example) then it never even looks at the options to consider throwing an
error.
>> freq = hist (data + 0, u)
freq =
13 7 8 7 12 10 10 3 10 12
>> freq = hist (data + 0, u,'invalidparameter')
freq =
13 7 8 7 12 10 10 3 10 12
>> hist (data + 0, u)
error: set: unknown property
error: called from
__bar__>bars at line 349 column 10
__bar__ at line 209 column 12
bar at line 124 column 18
hist at line 237 column 5
so, 1 - it seems there would have be a way for hist to check the 2nd or 3rd
input for 'validity', as they're the only two hist itself parses. 2 - it would
be useful for hist to actually name the property it has a problem with in the
error above.
