Simple HTML5 Charts using the canvas element


You can download the latest version of Chart.js from the GitHub releases or use a Chart.js CDN.

Selecting the Correct Build

Chart.js provides two different builds for you to choose: Stand-Alone Build, Bundled Build.

Stand-Alone Build


  • dist/Chart.js
  • dist/Chart.min.js

The stand-alone build includes Chart.js as well as the color parsing library. If this version is used, you are required to include Moment.js before Chart.js for the functionality of the time axis.

Bundled Build


  • dist/Chart.bundle.js
  • dist/Chart.bundle.min.js

The bundled build includes Moment.js in a single file. You should use this version if you require time axes and want to include a single file. You should not use this build if your application already included Moment.js. Otherwise, Moment.js will be included twice which results in increasing page load time and possible version compatibility issues. The Moment.js version in the bundled build is private to Chart.js so if you want to use Moment.js yourself, it's better to use Chart.js (non bundled) and import Moment.js manually.
