Making bins spaced evenly on a log scale with np.logspace

[GuillermoFidalgo]

This is more of a neat trick that can be used instead of making the number of bins > 10,000
and it doesn't have large sized bins at the beginning when setting x axis to log scale. 👍🏼

import numpy as np


# nbins = 30_000
nbins= 500
low = 0.25
up = 300
bins = np.logspace(np.log10(low),np.log10(up),num = nbins+1)
# h = df_mass.Histo1D(("Dimuon_mass", "Dimuon_mass", nbins, low, up), "Dimuon_mass")
h = df_mass.Histo1D(("Dimuon_mass", "Dimuon_mass", nbins, bins), "Dimuon_mass")

Now the histogram looks like this
