Selecting the Correct Build
Chart.js provides two different builds for you to choose: Stand-Alone Build, Bundled Build.
Stand-Alone Build
Files:
dist/Chart.jsdist/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
Files:
dist/Chart.bundle.jsdist/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.
Documentation
You can find documentation at www.chartjs.org/docs. The markdown files that build the site are available under /docs. Previous version documentation is available at www.chartjs.org/docs/latest/developers/#previous-versions.
