[Octave-bug-tracker] [bug #39552] quiver/quiver3 ignores scale with only one point to plot

[Nicholas Jankowski]

Follow-up Comment #23, bug #39552 (project octave):

findobj wolud be good. should keep from making fragile tests. but i don't have
a unique property to check yet. there are 3 children.  all 3 are type="line". 

(1) contains info about the origin of each arrow. just one xdata/ydata element
for each arrow, linestyle=none 
(2) contains info about the arrowhead line segments. three xdata/ydata
elements for each arrow (end-center-end), linestyle = -
(3) contains info about the arrow body segment. two xdata/ydata elements for
each arrow (base-tip), linestyle = -

so, should be able to find the one with the right number of xdata elements,
then use that one. will play with it a bit.
