[Gnuplot-info] how to draw a sphere that looks like a round sphere

[Zhong R. <re...@uc...>]

The sphere I draw in parametric mode looks flattened in z
direction, even I use 'set view equal xyz'.

I managed to use 'set view equal xy' and 'set view' to change
scale and scale_z.  My sphere is now close to round.  The
problem is that its vertical size keeps changing when I spin
the sphere or resize the window.

Could someone give a hint?  There must be a simple option to
make a sphere a perfect sphere no matter how you look at it.
