Managing disturbance

Hello ROOTers,
I have made a root file (cc.root).
But in this, there is lot of disturbance in the curve.
How can I remove the disturbance? Or to make the disturbance lessened ?

Thanks in Advance,

It is not clear what you mean by “disturbance”. You have drawn a histogram with error bars.
If you do not want to see the error bars draw your histogram with h1->Draw(“hist”).


Actually, I want to know, is it possible to make it in single line rather than this broad line?
Thanks in Advance,

Please read carefully my previous reply. There is no thick line, simply the fact that you draw your histogram with error bars.
