Hi all,

Strangely enough, I didn't find an answer to this question in the Roottalk
digest, although it must have been mentioned... My question is the
following: is is possible to use a TNtuple containing x, y and dy values to
draw a graph (histogram) of points x,y with errorbars y-dy to y+dy ?

Thanx,

Marco
