[Gnuplot-bugs] 3D polar plots

[<tho...@in...>]

  Hello=20

 Let me first congratulate to your very good  gnuplot Tool.
   It is really short and useful  !

 Here is one hint which may be useful for other users who need 3D Polar
coordinates=20

  If you want to plot the 3D polar function r(phi, theta) =20
  identify  phi =3D=3D u,  theta =3D=3D v,   and use parametric plot  :

  fx(u,v) =3D r(u,v) *cos(u)*sin(v)
  fy(u,v) =3D r(u,v) *sin(u)*sin(v)
  fz(u,v) =3D r(u,v)*cos(v)=20
  splot fx(u,v), fy(u,v), fz(u,v)   =20


                          best regards  T. Zettler=20
