react-chartjs-2

What is react-chartjs-2?

The react-chartjs-2 npm package is a React wrapper for Chart.js, a popular JavaScript library for creating simple yet flexible charts. It allows developers to create various types of charts such as line, bar, radar, doughnut, and pie charts, among others, with ease. The package provides React components that encapsulate Chart.js functionality, making it easy to integrate into React applications.

What are react-chartjs-2's main functionalities?

Line Chart

This code sample demonstrates how to create a simple line chart using react-chartjs-2. It includes a dataset for monthly sales and configures the chart to start the y-axis at zero.

{"import { Line } from 'react-chartjs-2';\n\nconst data = {\n  labels: ['January', 'February', 'March', 'April', 'May', 'June'],\n  datasets: [{\n    label: 'Monthly Sales',\n    data: [65, 59, 80, 81, 56, 55],\n    fill: false,\n    borderColor: 'rgb(75, 192, 192)',\n    tension: 0.1\n  }]\n};\n\nconst options = {\n  scales: {\n    y: {\n      beginAtZero: true\n    }\n  }\n};\n\nfunction MyLineChart() {\n  return <Line data={data} options={options} />;\n}"}

Bar Chart

This code sample shows how to create a bar chart with react-chartjs-2. It sets up a dataset with different colors for each bar representing votes for different options.

{"import { Bar } from 'react-chartjs-2';\n\nconst data = {\n  labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],\n  datasets: [{\n    label: 'Votes',\n    data: [12, 19, 3, 5, 2, 3],\n    backgroundColor: [\n      'rgba(255, 99, 132, 0.2)',\n      'rgba(54, 162, 235, 0.2)',\n      'rgba(255, 206, 86, 0.2)',\n      'rgba(75, 192, 192, 0.2)',\n      'rgba(153, 102, 255, 0.2)',\n      'rgba(255, 159, 64, 0.2)'\n    ],\n    borderColor: [\n      'rgba(255, 99, 132, 1)',\n      'rgba(54, 162, 235, 1)',\n      'rgba(255, 206, 86, 1)',\n      'rgba(75, 192, 192, 1)',\n      'rgba(153, 102, 255, 1)',\n      'rgba(255, 159, 64, 1)'\n    ],\n    borderWidth: 1\n  }]\n};\n\nfunction MyBarChart() {\n  return <Bar data={data} />;\n}"}

Doughnut Chart

This code sample illustrates how to create a doughnut chart using react-chartjs-2. It includes a dataset with three segments, each with its own color.

{"import { Doughnut } from 'react-chartjs-2';\n\nconst data = {\n  labels: ['Red', 'Blue', 'Yellow'],\n  datasets: [{\n    data: [300, 50, 100],\n    backgroundColor: [\n      '#FF6384',\n      '#36A2EB',\n      '#FFCE56'\n    ],\n    hoverBackgroundColor: [\n      '#FF6384',\n      '#36A2EB',\n      '#FFCE56'\n    ]\n  }]\n};\n\nfunction MyDoughnutChart() {\n  return <Doughnut data={data} />;\n}"}

Other packages similar to react-chartjs-2

recharts

Recharts is a composable charting library built on React components. It uses D3.js under the hood for sophisticated charting capabilities. Compared to react-chartjs-2, Recharts offers a more React-friendly API with the ability to compose charts using declarative components.

victory

Victory is another React chart library that provides an extensive collection of composable components for building interactive data visualizations. Victory charts are highly customizable and can be styled using standard inline styles, which might appeal to developers looking for a more integrated React experience compared to react-chartjs-2.

nivo

Nivo provides a rich set of dataviz components built on top of D3.js, with a strong emphasis on motion and interactivity. It offers a higher level of abstraction compared to react-chartjs-2 and includes a wide range of chart types with beautiful default styles and animations.

Properties

• data: PropTypes.object.isRequired,
• height: PropTypes.number,
• legend: PropTypes.object,
• options: PropTypes.object,
• redraw: PropTypes.bool,
• width: PropTypes.number

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link).

Thanks
