asymmetric error band?

Hi,
Is the asymmetric error band now implemented for TGraphxxx classes? If so, which is the first root version to have it? Can you provide an example or instructions? I can't get it to work in version 3.05/07. I found the exchange below in the roottalk archives.

It looks like I cannot draw asymmetric errors for a TH1, and I cannot draw a band for TGraph.
I guess I can do something clever,
like plotting 3 TH1's (or TGraphs),
and trying to shade the regions in between. However, I am not clever...

thanks,

The error band option is only available for histograms (see e1,2,3,4 options). We will implement it also for TGraphxxx classes.
