React Axis
An axis widget intended to replace generated D3 SVG with a React friendly component that supports timezones correctly.
Under the hood, it uses: d3.scale and d3.format moment.js and moment-timezone
SVG rendering is done with React.
This is a basic version of the functionality needed for a full charting application, but it's a start. It currently supports:
A general purpose Axis component
- Supports log, power and linear scales
- Supports animation between scales
- Can be positioned in different ways
A more specific TimeAxis component
- Supports arbitrary timezones
- Supports animations between scales
- Custom format functions
We will be merging this into react-timeseries-charts. Once that happens we'll bump this to v1.0.

Getting started

This React Axis component is intended to be installed with npm and the built into your project with a tool like Webpack. As it is a standalone axis component, most likely it should be used in another library, but who knows. Either way, it expects React to be present.
To install:
npm install react-axis --save
You can then import and use either the Axis or TimeAxis. In general the component is designed to be rendered within existing SVG (though it has a stand alone mode too):
import { TimeAxis } from "react-axis";

render() {
    return (
                width={800} height={50}


The repo contains the examples/ website. This is very helpful in developing new functionality. Within a cloned repo, you first need to run:
yarn install
This will install the development dependencies into your nodemodules/ directory.
You can then start up the test server, as well as automatic source building, by doing:
yarn run start-website
There is also a growing set of Jest tests, both for the components and utility code. The testing uses Jest's snapshot mechanism. To run, use:
yarn test
Visual materialization of the test examples can be accessed on the examples website at:
This setup is a work in progress.
