I have a problem with sns.histplot(). As far as I understand bins parameter should indicate how many of bins should be in the plot. Here is some code to visualize the strange (at least for me) behavior.

    d = {'col1': [1, 2, 3, 4, 5, 6, 7, 8, 9 , 10 , 11 , 12, 13, 14, 15], 'col2': [1, 1, 1, 1, 1, 1, 2, 2, 2 , 2 , 2, 2, 2, 2, 2]}
    df = pd.DataFrame(data=d)
    sns.histplot(data=df, x='col1', multiple='dodge', hue='col2', binwidth=2, bins=8)

I have almost same problem in my original code where i have

hist = sns.histplot(data=Data, x=y_data, multiple='dodge', ax=axes[0], hue=i[2][1], binwidth=2, bins=10)

And as You can see there is only one bin where data have its minimum and std but is not splitted into number of bins I declared. Can anyone explain me why this is not splitting data into provided number of bins ? How can I change code to ensure constant number of bins ?

I think the problem is binwidth parameter. Maybe just try to delete that parameter, or set it to smaller value (0.2 or 0.1)

CodePudding user response：

From the docs, regarding the binwidth parameter:

Width of each bin, overrides bins but can be used with binrange.

So you can't specify both bins and binwidth at the same time.
