[Octave-bug-tracker] [bug #39243] OpenGL: change to {x, y}data does not update bar()

[Ben Abbott]

Follow-up Comment #7, bug #39243 (project octave):

If I understand your question, my impression is that the value is "hidden". 
Essentially, something like below is happening.


sz = min (size (xdata), size (ydata));
xdata_to_return = xdata(1:sz(1),1:sz(2));
ydata_to_return = ydata(1:sz(1),1,sz(2));


The modified test you asked for is below.


h = patch (1 + [0 1 0 0], [0 0 1 0], 'b');
xdata = get (h, 'xdata');
ydata = get (h, 'ydata');
set (h, 'ydata', ydata(1:3))
get (h, 'xdata')

ans =

     1
     2
     1

set (h, 'ydata', ydata)
get (h, 'xdata')

ans =

     1
     2
     1
     1
