[Octave-bug-tracker] [bug #34417] patch() does not process 'cdata' correctly

[John W. Eaton]

Follow-up Comment #15, bug #34417 (project octave):

With the current version of Octave on my system, and with fltk+opengl
graphics, I see


xdata =

   0   0
   1   1
   1   0

octave:21> ydata = get (h, 'xdata')
ydata =

   0   0
   1   1
   1   0

octave:22> cdata = get (h, 'cdata')
cdata =

   0.71536   0.23336
   0.49571   0.26989
   0.57966   0.96610

octave:23> facevertexcdata = get (h, 'facevertexcdata')
facevertexcdata =

   0.71536
   0.23336
   0.49571
   0.26989
   0.57966
   0.96610


With gnuplot, I see
