THistPainter options ignored(?)

ROOT
1

I have a TH2D histogram, I do projections of each column and plot on single canvas. If

is my single column, I want to draw h as a line, therefore

But ROOT keeps drawing it as like with option “E”. Whatever I do, I have crosses, where width is a bin size, and height of the cross is my error. Draw() is ignoring all the options beside E1…E6, this have influence. GetOption() returns empty string. Is there some mechanism which overwrites options passed with Draw()?
How to make it listening to my wishes?

Try: h->Draw(“HIST L”);

Ok, this works. But with newly created histograms:

TH1D * h = new TH1D("h", "h", 10, -5, 5); h->FillRandom("gaus", 1000); h->Draw("L");
it works without 'hist". Where is the difference?

TH1D * h = new TH1D("h", "h", 10, -5, 5); h->Sumw2(); h->FillRandom("gaus", 1000); h->Draw("L"); // try "L" and "HIST L"

Ok, I see the points. Sumw2 matters. Thx!
