The problem is probably in __gnuplot_draw_axes__.m , lines 148-149

  fputs (plot_stream, "unset x2tics;\n");
  fputs (plot_stream, "unset x2tics;\n");

The second line should be

  fputs (plot_stream, "unset y2tics;\n");

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");

hAx(1) = subplot(3,1,1);
hAx(2) = subplot(3,1,2);
hAx(3) = subplot(3,1,3);

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 =

>> 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!
