Histogram with no vertical lines

ROOT
1

I know there is option “][” for not drawing vertical lines on edges of histogram. How can I do that for all the bins? Option Draw(“E SAME”) almost does the job, but when I do for all bins SetBinError(ibin,0.) to supress vertical error bar, I am loosing also the horizontal one.

Note that explanations for a lot functions at root.cern.ch/root/html/TH1.html are missing. Generaly speaking root documentation is not sufficient.

I found one stupid solution in a meanwhile. Istead of SetBinError(ibin,0.) one can use SetBinError(ibin,0.000001) such that errorbar is there but not visible. Then it works. Not that I am working in ptRoot environment as I need to work also with strings. It can work properly in pure root environment. Figure can found in the attachment (is not nice but the effect is there.)

Yes you need to see the horizontal bars only. What you are doing is fine.
