Matplotlib histogram bar width
2
I am using matplotlib histogram histtype='bar' to plot four datasets together. What it automatically does is that it changes the width of the bar of each dataset relative to the size of the dataset. I want to have equal bar width for all four datasets.
[n, bins, patches = plt.hist(
[np.sort(x2), np.sort(x3), np.sort(x4), np.sort(x5)],
bins=np.logspace(np.log10(8e-8), np.log10(1), 7),
histtype='bar',
weights=[w2,w3,w4,w5],
label=[
'$Delta {{chi}^2} <40$',
'$u_0 < 0.045$',
'${s}_{fitted} >5$',
'Multi-peaked'
]
)][1]

No, you set the bar width yourself via thebinsargument.

Thanks, but I’m not sure if I understand your point. My understanding is that the bins are the same for all datasets, so how does that determine the widths?

Oh, sorry, this kind of plot is really misleading. You kind of want a categorical histogram? I think you might decide to calculate the histogram first, then plot a barplot with the bars at the positions and widths you want.

The bins are actually the same size (numeric value) for each set but your x axis is logarithmic so it looks like the width is different. Try to plot a single dataset in a linear x axis (not logarithmic) and you will see that the widths of the bars are the same.

Thanks. I think you're right. Do you suggest a way to fix that? Because I need to keep the x axis in log scale.
– somayeh khakpash

The only way to keep x axis in log scale and show same width is to have different bin sizes with a logarithmin relation between then. Then they will be shown linearly (same width) in the x axis logarithim plot.
