[Gnuplot-info] True scale isometric plots

[Alan B. <br...@co...>]

I am plotting a ray trace in 3D using splot.  Is there any simple way of
setting the three axes to the same scaling (units per inch) so that the
isometric view is not distorted except for the fact that it is an
isometric view.  I wish circles to be circles if viewed normal to the
plane they are in.
