The tickStep() function in D3.js is used to return the difference between the adjacent tick values in the array.
Syntax:
tickStep(start,stop,count);
Parameters: This function accepts three parameters as mentioned above and described below:
- start: It is the starting value from where we want the array element to be, it is inclusive.
- stop: It is the starting value to which we want the array element to be, it is inclusive.
- count: It is the number of elements we want in a given start and stops range.
Return value: It returns that step value in floating point representation.
Below given are a few examples of ticks() function
