[Octave-bug-tracker] [bug #47149] line ([x1, x2]', [y1, y2]) works in Matlab but not Octave

[Lachlan Andrew]

Follow-up Comment #6, bug #47149 (project octave):

Good point, jwe.  I was totally forgetting that it is possible to access the
data again.

The reason I wasn't getting any line was that I was drawing vertical lines,


  line ([x1, x1]', [y1, y2])


and so each line was reduced to a single point.

Fortunately, Matlab gives


>> h = line ([1,2]', [3,4])
h =
  173.0011
>> get (h, {'xdata', 'ydata'})
ans = 
    [1x2 double]    [1x2 double]


so it seems we can just transpose the data -- much better than having to
modify some subset of graphics toolkits to reinterpret the data.

Similar to your last example, Octave gives a diagonal line for the one-shot
command


 line ('xdata', [1, 2]', 'ydata', [3, 4]);


Thanks for all your guidance.
