Hello

:From octave ver 3, the axis command (also other plot related commands like 
xlabel) should be executed
after plot command.
(This way is compatible to that of the current MATLAB. )

plot command
plot related command like axis, xlabel, etcs.
drawnow(); (if required for example plot command in loop)

Regards

Tatsuro
