Difference Chart: Cheating with the Domain
Explore how to create difference charts in D3.js by managing the y-axis domain for better visuals while balancing data accuracy. Understand the use of datum for binding static data and learn how to implement clip paths for visual separation of chart areas. This lesson helps you refine chart aesthetics and data representation effectively.

Difference chart code
Explanation
Lines 98-105: The observant D3.js reader will have noticed that the setting of the y domain has a large section commented out.
That’s because I want to be able to provide an ideal way for the graph to represent the data in an appropriate range. But because we are using the basis smoothing modifier and the data is “peaky,” there is a tendency for the y scale to be fairly broad and the resultant graph looks a little lost:
Alternatively, we could remove the smoothing and ...
