This wasn’t in the specs, I know so feel free to say "No - you should have asked that when we started," but could we have the ability to have the interval change on the x-axis say from decades to years?
This is a "nice-to-have" feature. Because the Y-axis already offers similar functionality, the existing code should serve as a guide to anyone looking to implement this.
