Hi Basu,
here my remarks on the patch. It applies perfectly and in almost all cases
which I tested it fixes the bug. I only found the following case, where
setting the aspect ratio seems still to be ignored:
{{{
var('x,y')
P=plot3d(x^2-9*y^2,(x,-3,3),(y,-1,1))
P.aspect_ratio((1,1,1))
P.show()
}}}
is different from
{{{
var('x,y')
P=plot3d(x^2-9*y^2,(x,-3,3),(y,-1,1))
P.show(aspect_ratio=(1,1,1))
}}}
furthermore I observed that by this patch
{{{
P.show(aspect_ratio=(1,2,3))
}}}
changes the value of
{{{
P._aspect_ratio
}}}
and thus also the behaviour in all following show() commands. One can
surely discuss if this is usefull or not, but I think in the 2d plots the
setting of aspect ration in a show command only affects this plot and not
the following. I think the 3d behavior should be consistent.
