Details:

Hello,
 
 consider the following example:
 clf
 x = 0:0.1:2*pi; 
 y1 = sin (x);
 y2 = exp (x - 1);
 ax = plotyy (x, y1, x - 1, y2, @plot, @semilogy);
 axes(ax(1)); text(2, .5, 'A');
 axes(ax(2)); text(3, 20, 'B');
 
Expected output: two curves, two vertical axes, one combined horizontal axis,
and two letters inside the graph. 
 
Matlab output (7.8.0.347 (R2009a)): after axes(ax(1)), the second figure
disappear. After axes(ax(2)), it gets back, but then the x axis is
overwritten.

Octave 3.2.4 output: after the first 'text' command, the second drawing is
compressed horizontally. The second text command has no visible effects. 


Enclosed a patch I got from Liam Groener (address@hidden), solving this
problem

Regards

Pascal
