Hello together,

I would like to plot a circle in a 3d plot [direct graphics], where the
axes are not isotropic. The circle should lie in the y plane. If I use
data coordinates I have to know the aspect ratio of z and y axis and
have to generate an ellipse ? In 2d I could use usersym where this
scaling is done automatically, but in 3d ?
How to get the ratio between the two axes ?
How to get the ellipse ?

Thanks for your help in advance !
