Fixed in version 3.4.  Please upgrade to eliminate this bug.

I tested the example with the developer's sources. This bug has been fixed. I've attached equal.png to demonstrate the result.

In 3.2.4, using axis('equal') with a pcolor plot squashes the plot vertically to a single line.  This seems to happen with either X11 or wxt.


[x,y]=meshgrid([0:100],[0:100]);
z=exp(-(x/20).^2-(y/20).^2);

pcolor(x,y,z);shading flat;
pause

axis('equal');
pause

imagesc(x,y,z);
axis('xy','equal');


At the first pause, it's ok (but unequal); it fails at the second one.  imagesc is fine.  No problems with 3.0.1 using either gnuplot 4.2 or 4.4.
