Plot variances in each bin

ROOT
1

Hi,

  1. Is there any way to plot variance of Y (in each bin) against X?..
    I mean the S(J)^2 (in the ProfileX) vs X.

Does S(J) is doing the same as Sx =sqrt ( sum_i^N (x_i - x_mean)^2 / N ?

Will GetBinError do that?

  1. Does the mean [h(J)] mentioned in the ProfileX, include any weighting factor?
    Like in the common formula of an average we get = Sum_i (x_i*w_i)/ Sum w_i
    Where, w_i is the weight factor.

If yes, then what kind of weighting? If not, then how to include?

Please read tips for efficient and successful posting and posting code

May be @moneta has an idea.

Is there a way to use “s” and a “cut” together while using ProfileX? As I can see that there is only one place for option.
