Happy New Year!
I want to find the error bars of data points in the x- and y- axes to plot a TGraph with error bars. Please suggest how can I calculate this from the root histogram (attached root file). In the attached root file I need error bars of “dN_dPt” histogram data points with a logarithmic scale on the y-axis.
