Refining Scales
Explore how to refine your scales in scatter plot visualizations with D3.js. Learn to apply the nice function to round domain values, use rangeRound for output rounding, and clamp to limit values within the output range. Understand when and why to apply these techniques to improve your data accuracy and chart clarity.
We'll cover the following...
We are going to look at how to refine our scales. We can change the behavior of a scale by chaining additional functions. Let’s explore what else we can do with scales.
The nice() function
The first function we will explore is called nice(). There are times where our dataset can contain decimal values. We would not always be dealing with whole numbers. Depending on the type of chart we are drawing, it may not be essential to scale a decimal value. We can tell our scale function to round the domain values. That’s what the nice() function does. ...
