Hello, in TMultiGraph::Draw doc, it is written that “Options to draw a graph are described in TGraph::PaintGraph”. Yet, if I click on the link to TGraph::PaintGraph, I see that the documentation is rather empty. Does it point to the correct stuff or does the documentation of this function is still in progress?
It should point to root.cern.ch/root/html534/TGraphPainter.html
The class TGraphPainter was implemented after TMultiGraph I will change that.
Thanks.
Done
I do not see any change in the text of TMultiGraph::Draw. It still refers to TGraph::PaintGraph. Is it normal?
Yes, the doc is not rebuild each time a change is done. Note that is you go on the top of the TMultigraph page you will get the correct reference.
Ah ok, thanks. 
Still a question, in the first example given in TMultiGraph (on the top), I see that a lot of option are given to Draw
If I read the TGraphPainter doc, I do not find any information about “d” option. Sorry, if I do not read correctly. Probably it is not a “d” option but a “l3d” option but there is also nothing about this option. Am I right?
It is documented here:
root.cern.ch/root/html534/TMultiGraph.html
the example shows it by himself…it is the 3D option … and L is for “line”… as for any other graph.
