Details:

I tried to create a column of three subplots where the second plot has its
y-axis on the right-hand side. Example code:


graphics_toolkit ("gnuplot");

figure(1)
clf;
hAx(1) = subplot(3,1,1);
plot(5,5);
hAx(2) = subplot(3,1,2);
plot(10:-1:1);
hAx(3) = subplot(3,1,3);
plot(10:20)
set(hAx(2),"yaxislocation","right")


For some reason the third plot has a correct y-axis on the left side, but
additionally the y-axis of the second plot on the right (see attached
screenshot). Scrolling in the third subplot vertically moves both y-axes, so
they seem to belong to one axis object, not two on top of each other.
I cannot even find the duplicate yticklabels:


>> get (1,"children")
ans =

  -201.90
  -207.46
  -213.86
>> get(get(1,"children")(1),"yticklabel")
ans =
{
  [1,1] = 10
  [1,2] = 12
  [1,3] = 14
  [1,4] = 16
  [1,5] = 18
  [1,6] = 20
}


(Note that the first child of the figure is the lowest axis object)

I am using Octave 4.0.0-rc4 under Windows 7 with the bundled Gnuplot 4.6
binary.

Thanks for any help!
Martin
