*Summary:* This example shows how to create a one-dimensional histogram of a data samples in F#.

let's first create some data for the purpose of creating example charts:

In [3]:

```
open Plotly.NET
let rnd = System.Random()
let x = [for i=0 to 500 do yield rnd.NextDouble() ]
```

A histogram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.
The histogram chart represents the distribution of numerical data and can be created using the `Chart.Histogram`

function:.

In [4]:

```
let histo1 =
x
|> Chart.Histogram
|> Chart.withSize(500.,500.)
```

In [ ]:

```
histo1
```
