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:Â It returns that step value in floating point representation.
Below given are a few examples of ticks() function
Example 1:
HTML
<!DOCTYPE html> < html lang = "en" > < head >   < meta charset = "UTF-8" >   < meta name = "viewport"          content = "width=device-width, initial-scale=1.0" >   < title >D3 tickStep() Function</ title > </ head > < body >   <!--fetching from CDN of D3.js -->   < script type = "text/javascript"    </ script >   < script >     // Choosing 10 elements in a range     let step=d3.tickStep(10, 20, 10);     console.log("Difference between each tick value is: ",step);         </ script > </ body > </ html > |
Output:
Example 2:
HTML
<!DOCTYPE html> < html lang = "en" > < head >   < meta charset = "UTF-8" >   < meta name = "viewport"          content = "width=device-width, initial-scale=1.0" >   < title >Document</ title > </ head > < body >   <!--fetching from CDN of D3.js -->   < script type = "text/javascript"    </ script >   < script >     // Choosing 1000 elements in a range     let step=d3.tickStep(10, 15, 1000);     console.log("Difference between"+                 " each tick value is: ",step);     </ script > </ body > </ html > |
Output:
Example 3: If the stop is less then start
HTML
<!DOCTYPE html> < html lang = "en" > < head >   < meta charset = "UTF-8" >   < meta name = "viewport"          content = "width=device-width, initial-scale=1.0" >   < title >Document</ title > </ head > < body >   <!--fetching from CDN of D3.js -->   < script type = "text/javascript"    </ script >   < script >     // Choosing 1000 elements in a range     let step=d3.tickStep(10, 5, 1000);     console.log("Difference between"+                 " each tick value is: ",step);     </ script > </ body > </ html > |
Output:
