Unwanted vertical lines in TH1

Hi,

I just started using ROOT and I want to read some data from a file and create a histogram. However I found that there are some vertical lines in the histogram and I want to remove them. How can I do that.

Also is it possible to set the range when I fit the histogram. Say fit only x>2, while showing all the data.

Thank you.

remove :

c1->SetGrid();

Thank you for your reply.

I may not be clear enough, I don’t mean to remove the grid, what I want is to remove the blue lines that pass through marker.


Try:
h1->Draw(“HIST”); // “HIST” or “HIST P”

or:

h1->Sumw2(0);
h1->Draw();

This solved my problem, thank you
