[ROOT] 'bar' and 'SetRangeUse' plot option for TGraph::Draw(Option_t *option)

Hello!

I used the TGraph routine
[..]->Draw("ABP");
to draw a graph with bars instead of connecting the points with lines. 

1.) Is there a possibility to vary the bar width of the points?
2.) TAxis::SetRangeUser(..) can just be varied between the first and the last 
entry. What do I have to do to set the axis window even larger than the 
spread of the points on the axis?

Thanks in advance!

Cheers,

Ralph Steinhagen



void TAxis::SetRangeUser(Axis_t ufirst, Axis_t ulast)
{
//  Set the viewing range for the axis from ufirst to ulast (in user 
coordinates)
//  To set a range using the axis bin numbers, use TAxis::SetRange.

   SetRange(FindBin(ufirst),FindBin(ulast));
}
