SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| None | 0 | Does not attempts to automatically calculate an optimum bin width and preserves the current histogram organization. | |
| Scott | 1 | Calculates the optimum bin width as 3.49σN, where σ is the sample standard deviation and N is the number of samples. | |
| Sturges | 2 | Calculates the optimum bin width as ceiling( log2(N) + 1 )m where N is the number of samples. The rule implicitly bases the bin sizes on the range of the data, and can perform poorly if n < 30. | |
| SquareRoot | 3 | Calculates the optimum bin width as the square root of the number of samples. This is the same rule used by Microsoft (c) Excel and many others. |
