D3.js quantileSorted() Method

With the help of d3.quantileSorted() method, we can get the quantile value of the given array of sorted values by using p as a probability in this method.

Syntax:

d3.quantileSorted(array, p)

Parameter: This function has the following parameter as mentioned above and described below:

• array: It is an array of values which is passed as parameter.
• p: It is the quartile range value.

Return Value: It returns the p-quantile of the given sorted array of elements.

Note: To execute the below examples you have to install the d3 library by using this command prompt we have to execute the following command.

npm install d3

Example 1: Filename: index.js

In this example we can see that by using d3.quantileSorted() method, we are able to get the p-quantile value from the given sorted values of an array by using this method.

// Defining d3 contrib variable
var d3 = require('d3');

var arr = [1.21, 1.33, 1.33, 1.34, 1.37, 1.37, 1.38,
1.4, 1.42, 1.43, 1.43, 1.43, 1.44, 1.45, 1.45, 1.45,
1.45, 1.45, 1.45, 1.45]

var gfg = d3.quantileSorted(arr, 0.25)

console.log(gfg)

Output:

1.37

Example 2: Filename: index.js

// Defining d3 contrib variable
var d3 = require('d3');

var arr = []
for(var i = 0; i < 50; i++) {
    arr.push(i);
}

var gfg = d3.quantileSorted(arr, 0.75)

console.log(gfg)

Output:

36.75

Note: The above program will compile and run by using the following command:

node index.js
