D3.js areaRadial.outerRadius() Method

The areaRadial.outerRadius() method is used to set or return the outerRadius accessor of the areaRadial. It can be a number or a function that returns a number representing the outerRadius of our areaRadial.

Syntax:

 areaRadial.outerRadius(outer_Rad);

Parameters: This method accepts single parameter as mentioned above and described below:

  • outer_Rad: This parameter holds the outerRadius that can be a number or a function returning the outerRadius.

Return Value: This method returns the outerRadius accessor function of the area radial.
