Customizing d3.js chart | the D3 Graph Gallery

Axis

D3.js offers built-in function to add axis to your chart. The first step is to build a scale that allows to transform a numeric value to a coordinate on the plot. The second is to call axisBottom() or axisLeft() to build the axis. Browse the example below to understand the different types of existing scale, how to build axis and how to customize them.

Basic linear axis

The most basic linear axis you can do in d3.js. Keeping only the core code.

Categorical axis with scalePoint()

The scalePoint() allows to build a categoric axis. Simple example keeping only the core code.

Categorical axis with scaleBand()

Slightly different from the previous example: this method is adapted for barplot or boxplot where each category uses a range of the axis.

Vertical axis
