Hi Gilles,

This is possible with histograms only, not with TGraphs.
To selecet this option, do:
   hist->Draw("e3");

This option could also be implemented on TGraph. However, TGraph assumes
that points can be non-ordered along X. This would add a compication.

I am trying to draw and fill  an error bar area on a graph. By error bar
area,
I mean  the area between the two curves going through the extremities of
the
error bars of graph points. Does anyone know if there exists such an
option
or how to do it otherwise?
Thanks a lot for any help
