hello,
In encounter rthe follwoing problems with error bars on TH1F:
1/I put some errors to one histo in my analysis.
Now I can't get rid of them when plotting it!
h1->Draw("P") still draws the error bars...Is there a way of drawing
only the points values?
2/I have a ntuple with "x y sigma_y". Is there a direct way to plot
y vs x with sigma_y errors on y (other than MakeClass...)?
3/I plot some histos on my canvas.
I then want to add some points from a tuple.
when I incoporate
"tuple->Draw("y:x","",""same");
to my script I don't see any oupput (even with a c1->Update)
if I do it interactively it works...
(I am using Root3.05)
thanks
stephane
