Details:


clear
a=1
b=1
t=0:.01:2*pi;
x=a*(cos(t);
y=b*(sin(t);
axes=("square")
plot(x,y)


Display of the graph is actually oval shaped and the grid is rectangular
Saving the plot as pdf carries the distortion through
I dont have a postscrip viewer so I cannot tell if it is also distorted , but
have included the file 

 The tick marks indicate the grid should be square and the shape a circle.

I presume it to be issue with monitor aspect ratio and a gnuplot problem but
see no opportunity to correct the problem in the GUI Octave version.

Monitor resolution is 1920x 1080 Aspect ratio 16:9
Changing resolution does not affect the issue



Windows 7 PRO 64 bit
