laravel-chartjs - A Chart.js wrapper for Laravel

Simple package to facilitate and automate the use of charts in Laravel using the Chart.js library.

Setup:

This package provides a wrapper for Chartjs that allows it to be used simply and easily inside a Laravel application. The package supports a number of installation methods depending on your needs and familiarity with JavaScript.

1. Installing this package

For older versions of Laravel (8 and below), add the Service Provider in your file config/app.php:

Publishing the config file to your own application will allow you to customise the package with several settings such as the Chartjs version to be used and the delivery method for the Chartjs files.

2. Installing Chartjs

Next, you can install and add to your layouts / templates the Chartjs library that can be easily found for download at: http://www.chartjs.org

There are several installation options for Chartjs. By default, this package comes set to use the 'custom' self-managed delivery method (to avoid conflict with existing installations). You can also select from several other delivery methods:

CDN

For rapid development and testing between versions, you can easily set the delivery method to 'CDN' in the config\chartjs.php settings, this will load the specified Chartjs files via an external content delivery network. Chartjs versions 2, 3 and 4 are available by CDN. These also load Moment.js and Numeral.js which are commonly needed for business charts.

Publish

If you do not use JavaScript packages anywhere else in your application or are new to JavaScript development then you may not already have the Node Package Manager, Laravel Mix or Vite set up. In that case, this package includes pre-compiled versions of Chartjs that you can use in your application. To publish the chart.js binary to your application's public folder (where JavaScript bundles are stored) you can publish the package's pre-built distribution assets.

By default, the publish method will install Chartjs version 4 using the latest binary in the package. If you want to publish an older version, we have also included the latest stable Chartjs releases for version 3 and version 2. You can publish these to your public assets folder using the following commands:

Binary

In some rare circumstances such as local development without an internet connection, private applications, shared servers or where you cannot access the public folder on your server, then you may wish to have end-users directly load the binary files. This method is not recommended because it streams the contents of the files from inside your application. This delivery method will load the Chartjs files normally published to your assets folder directly from inside your vendor folder. To use this method, set the delivery config variable to 'binary' and choose the Chartjs version you wish to use in the config file.

NPM (Recommended)

The recommended method to install Chartjs in a web application is to include it in your normal JavaScript and/or CSS bundle pipeline using NPM, Laravel Mix or Vite. For instructions on this method of installation please visit: https://www.chartjs.org/docs/latest/getting-started/

Usage:

You can request to Service Container the service responsible for building the charts and passing through fluent interface the chart settings.

The builder needs the name of the chart, the type of chart that can be anything that is supported by Chartjs and the other custom configurations like labels, datasets, size and options.

In the dataset interface you can pass any configuration and option to your chart.All options available in Chartjs documentation are supported. Just write the configuration with php array notations and it works!

Advanced Chartjs options

The basic options() method allows you to add simple key-value pair based options. Using the optionsRaw() method it's possible to add more complex nested Chartjs options in raw json format and call the options for plugins:

Passing string format like a json

Examples

1 - Line Chart:

2 - Bar Chart:

3 - Pie Chart / Doughnut Chart:

Advanced Custom Views

If you need to edit the underlying Blade component (to adjust CDN logic or deeper CSS changes to the <canvas> element used to render the charts), you can publish the views:

You can then customise the published Blade file at ./views/vendor/laravelchartjs/chart-template.blade.php in your application.

To revert any customisation, simply delete or rename this file from your application.

Livewire Support

This package has prototype support for live updating on Livewire. See the demo repo

Legacy Support

This package also supports older versions of Laravel and Chartjs. The previous syntax for building charts is still supported and can be accessed via the app()->chartjs method. The previous blade rendering syntax is also still supported, and can be accessed via the {{ app()->chartjs()->render() }} directive. The legacy syntax is particularly useful for migrating to this package from the previous versions of this package.

Issues

This README, as well as the package, is in development, but will be constantly updated, and we will keep you informed. Any questions or suggestions preferably open a discussion first before creating an issue.

Provenance

Some of the original logic for this package was originally developed by Brian Faust. The main package from which this current version of the package is forked was primarily developed and maintained by Felix Costa. In 2024, the package was adopted by Icehouse Ventures which is an early-stage venture capital firm based in New Zealand. We use Chartjs heavily in our Laravel applications and want to give back to the Laravel community by making Chartjs fast and easy to implement across all major versions and to streamline the upgrade path.
