That is almost what I am looking for, although I would like to have better
looking coordinate axes. I like the boxes that TH2F creates, with three
axes, including labels and tickmarks. I would much rather put the tornado in
one of these coordinate systems than drawing my own axis.
Thanks for your reply,
Reinhard

The macors:
http://root.cern.ch/root/html/examples/tornado.C.html
and
$ROOTSYS/tutorials/basic3d.C
show how the classes:
http://root.cern.ch/root/html/TPolyMarker3D.html
http://root.cern.ch/root/html/TPolyLine3D.html
can be used.
More advanced example (drawing the primitive axis) can be found:

yLine3D:Axis
Hope this helps,
