Freedman-Diaconis Rule
The Freedman-Diaconis Rule says that the optimal bin size of a histogram is $$ \text{Bin Size} = 2 \cdot \text{IQR}(x) n^{-1/3}$$ where $x$ is the data and $n$ is the number of observations in the data …

What to do when IQR returns 0 in Freedman-Diaconis' rule?
For discretization, I'm using Freedman-Diaconis rule which computes the optimal number of bins which will be given input to KBinsDiscretizer. … Freedman-Diaconis' rule states that,
$$ \text{bin width}, h=2\frac{\operatorname{IQR}(x)}{n^{1/3}} $$
$$ \text{number of bins}, k = \frac{range(x)}{h} $$
The column has $32561$ values. …

Scott's and Freedman–Diaconis rules of the thumb for selecting bin width - disatvantages
Scott's and Freedman–Diaconis rules of the thumb are based on the following formula:
In the article here it is stated that:
While these appear to be useful estimates for unimodal densities … My question is, will Scott and Freedman–Diaconis rules of the thumb estimate the correct number of bins on distributions with more than one peak? …

Optimal number of bins in histogram by the Freedman–Diaconis rule: difference between theore...
Wikipedia reports that under the Freedman and Diaconis rule,
the optimal number of bins in an histogram, $k$ should grow as
$$k\sim n^{1/3}$$
where $n$ is the sample size. … The Freedman–Diaconis rule is:
$$h=2\frac{\operatorname{IQR}(x)}{n^{1/3}}$$ …

Derivation/Explanation of the Freedman-Diaconis Rule
Can anyone provide a good derivation of the FD rule? Or explain why it is a good way to define the bin widths of a histogram. Are there any other similar rules and how do they compare?

Computing histogram bins with insensitivity to domain scale
Currently, I'd like to use the Freedman-Diaconis rule for determine bin widths:
$h=2\times\text{IQR}\times N^{-1/3}$ (where $h$ is the bin width). … The problem with this is that each dataset would have a different IQR, and thus a different recommendation for the bin width according to Freedman-Diaconis. …

Knuth rule for number of bins of a histogram vs. chi2 fitting
The Knuth rule (I have some bimodal cases so I'm not using Freedman-Diaconis or Scott) gives me the following histogram (there are 914 data points):
