What is @elastic/charts?

@elastic/charts is a powerful charting library developed by Elastic. It provides a wide range of chart types and is designed to be highly customizable and performant. It is particularly well-suited for creating complex, data-driven visualizations in web applications.

What are @elastic/charts's main functionalities?

Line Chart

This code sample demonstrates how to create a simple line chart using @elastic/charts. The LineSeries component is used to define the data and the axes for the chart.

import { Chart, LineSeries, Settings } from '@elastic/charts';

const data = [
  { x: 0, y: 2 },
  { x: 1, y: 3 },
  { x: 2, y: 5 },
  { x: 3, y: 7 },
];

const LineChart = () => (
  <Chart>
    <Settings showLegend={true} legendPosition="right" />
    <LineSeries
      id="lineSeries"
      xScaleType="linear"
      yScaleType="linear"
      xAccessor="x"
      yAccessor="y"
      data={data}
    />
  </Chart>
);

Bar Chart

This code sample demonstrates how to create a bar chart using @elastic/charts. The BarSeries component is used to define the data and the axes for the chart.

import { Chart, BarSeries, Settings } from '@elastic/charts';

const data = [
  { x: 'A', y: 30 },
  { x: 'B', y: 80 },
  { x: 'C', y: 45 },
  { x: 'D', y: 60 },
];

const BarChart = () => (
  <Chart>
    <Settings showLegend={true} legendPosition="right" />
    <BarSeries
      id="barSeries"
      xScaleType="ordinal"
      yScaleType="linear"
      xAccessor="x"
      yAccessor="y"
      data={data}
    />
  </Chart>
);

Pie Chart

This code sample demonstrates how to create a pie chart using @elastic/charts. The Partition component is used to define the data and the structure of the pie chart.

import { Chart, Partition, Settings } from '@elastic/charts';

const data = [
  { category: 'A', value: 30 },
  { category: 'B', value: 80 },
  { category: 'C', value: 45 },
  { category: 'D', value: 60 },
];

const PieChart = () => (
  <Chart>
    <Settings showLegend={true} legendPosition="right" />
    <Partition
      id="pieChart"
      data={data}
      valueAccessor={(d) => d.value}
      valueFormatter={(d) => `${d} %`}
      layers={[
        {
          groupByRollup: (d) => d.category,
          shape: {
            fillColor: (d) => d.category === 'A' ? 'red' : 'blue',
          },
        },
      ]}
    />
  </Chart>
);

README

Elastic Charts

🚨 WARNING While open source, the intended consumers of this repository are Elastic products. Read the FAQ for details.

---

You should check out our living style guide, which contains many examples on how charts look and feel, and how to use them in your products.

Installation

To install the Elastic Charts into an existing project, use the yarn CLI (npm is not supported).

yarn add @elastic/charts

Running Locally

Node

We depend upon the version of node defined in .nvmrc.

You will probably want to install a node version manager. nvm is recommended.

To install and use the correct node version with nvm:

nvm install

Development environment

You can run the dev environment locally at http://localhost:9001 by running:

yarn
yarn start

We use storybook to document API, edge-cases, and the usage of the library. A hosted version is available at https://elastic.github.io/elastic-charts.

Goals

The primary goal of this library is to provide reusable set of chart components that can be used throughout Elastic's web products. As a single source of truth, the framework allows our designers to make changes to our look-and-feel directly in the code. And unit test coverage for the charts components allows us to deliver a stable "API for charts".
