The pow.rangeRound() function is used set the range of the scale to the specified array of values along with this it internally sets the interpolator to interpolatorRound.
Syntax:
pow.rangeRound([range]);
Parameters: This function takes a single parameter that is given above and described below.
- [range]: This is an array that contains the range for the domain specified.
Return Values: This function does not return anything.
Below given are a few examples of the function given above.
Example 1: When elements in range array are of type number.
