Error bars

Hi Rooters,

I have been using the demo example given in Chapter 4 (Graphs), page 53, in User's guide. This program draws markers with different colours taking input from graph, i.e.,

Double_t *nx = gr3->GetX();
Double_t *ny = gr3->GetY();

I wanted to ask is there any way with which it can take errors too........ Something like :

Double_t *nex = gr4->GetEX();
where gr4 is TGraphErrors and EX is the error on x Is it possible?

Thanks
