Both Chart.js and ECharts are JavaScript libraries that help developers create beautiful charts and graphs on websites. Chart.js is known for being simpler and easier to learn, perfect for basic charts, while ECharts offers more complex visualizations and features. These libraries are commonly used when you need to turn data into visual graphs, like pie charts, bar graphs, or line charts on dashboards.
Both libraries support various chart types, including line, bar, pie, and scatter charts. However, echarts has more advanced features like 3D charts, heatmaps, and treemaps. Chart.js has better support for animations and transitions.
Both libraries have TypeScript definitions, but chart.js has more comprehensive support.
Both libraries support modern browsers, including Chrome, Firefox, Safari, and Edge. However, chart.js has better support for older browsers like Internet Explorer.
Chart.js has no dependencies, while echarts depends on zrender, a graphics rendering library.
Chart.js is generally faster and more lightweight than echarts, especially for large datasets.
Both libraries are compatible with popular frameworks like React, Angular, and Vue.js.
Chart.js has a more active community, with more contributors and issues closed on GitHub.
Both libraries have good documentation, but chart.js has more tutorials and examples.
Both libraries are actively maintained, with regular updates and bug fixes.
1const ctx = document.getElementById('chart').getContext('2d');
2new Chart(ctx, {
3 type: 'line',
4 data: {
5 labels: ['Jan', 'Feb', 'Mar'],
6 datasets: [{
7 label: 'Sales',
8 data: [10, 20, 30],
9 backgroundColor: 'rgba(255, 99, 132, 0.2)',
10 borderColor: 'rgba(255, 99, 132, 1)',
11 borderWidth: 1
12 }]
13 }
14});This code creates a simple line chart with Chart.js, displaying sales data for January, February, and March.
1var chartDom = document.getElementById('chart');
2var myChart = echarts.init(chartDom);
3var option;
4option = {
5 xAxis: {
6 type: 'category',
7 data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
8 },
9 yAxis: {
10 type: 'value'
11 },
12 series: [{
13 data: [120, 200, 150, 80, 70, 110, 130],
14 type: 'bar'
15 }]
16};
17myChart.setOption(option);This code creates a simple bar chart with ECharts, displaying data for each day of the week.
Chart.js is a better choice for smaller applications or those requiring faster performance, while echarts is more suitable for complex, data-intensive applications.
A comprehensive charting library that creates beautiful interactive charts. It includes scientific charts, 3D graphs, and statistical tools built-in.
Like Chart.js and ECharts, it offers ready-to-use charts but with more scientific and statistical features. It's particularly good for dashboards and data science applications.
Interactive Charting LibraryModern charting library that creates interactive visualizations with smooth animations. It works well on mobile devices and offers many customization options.
Similar feature set to Chart.js but with better animations and modern design. It's particularly good for creating responsive charts for mobile-first applications.
Interactive Charting LibraryA powerful JavaScript library for creating custom data visualizations in the browser. It gives you complete control over how your charts look and behave by manipulating web elements (SVG, Canvas, HTML).
While it has a steeper learning curve than Chart.js, D3.js offers much more flexibility and control. It's perfect when you need highly customized charts that Chart.js or ECharts can't provide out of the box.
Data Visualization LibraryProfessional-grade charting library with extensive features and chart types. While it requires a license for commercial use, it's free for personal and non-profit projects.
More feature-rich than Chart.js and ECharts, with excellent documentation and support. It's particularly good for enterprise applications where reliability and support are crucial.
Enterprise Charting LibraryA React-specific charting library that makes it easy to add charts to React applications. It provides simple components that work well with React's component model.
Great alternative if you're working specifically with React. It follows React patterns and is easier to integrate with React applications than Chart.js or ECharts.
React Charting LibraryAll the links point to the new version 4 of the lib.
In case you are looking for an older version of the docs, you will have to specify the specific version in the url like this: https://www.chartjs.org/docs/2.9.4/
Instructions on building and testing Chart.js can be found in the documentation. Before submitting an issue or a pull request, please take a moment to look over the contributing guidelines first. For support, please post questions on Stack Overflow with the chart.js tag.
Chart.js is available under the MIT license.
