The d3.line.x() method sets or gets the x accessor point of the line. If x is provided, it must be a number or a function that returns a number.
Syntax:
d3.line.x(x-point);
Parameters:
- x-point: This method takes an x-point that can be set from the points array.
Return Value: This method returns the x accessor point of the line.
Example 1: Setting the x-point using this method. For y-points here we have used line.y() function.
