Hallo,
I would like to do a 4d scatter plot like the one in the link below:
root.cern.ch/drupal/category/ima … ics?page=1
(3rd row from the bottom)
but i have found no documentation/examples and for me it is not apparent how to do it.
do i use a TGraph2D? and how do i put the 4th dimension?
thanks,
theodoros
