PHPChartJS

PHP OOP library for ChartJS

PHPChartJS acts as an interface between the ChartJS library and the server side code. Set up a chart in no time and have every aspect of the graph managable from your PHP code. This interface is set up to provide code completion in every scenario so you never have to guess or lookup what options are available for the chosen chart. The library is entirely object oriented.

This library is still in active development and aims to implement all options ChartJS has to offer. Check the Configuration milestone to view the progress of implementing all existing options.

Example use

`` The result generated by rendering the chart will look something like this:

`

Callbacks

You can provide javascript callbacks with ease:

``

Rendering

Rendering the chart creates some HTML and some JavaScript. The JavaScript contains a JSON object providing the necessary configuration for ChartJS. Every part of the configuration can be cast to an array or a JSON object.

Render isolated part of the configuration:

``

Or return an array containing the set configuration:

``

Pretty mode

If you're not a fan of the long lines of code that are being generated you can force the rendering to be done in pretty mode, see the following example.

Configuration options

Every option that is supported by ChartJS will be made available in this library.

Layers

ChartJS requires you to build a JSON object containing the configuration options you want to set for the current chart. These options are spread over multiple layers inside the configuration object. Accessing these layers with PHPChartJS is super easy.

Let's say we wanted to access the chart's getAnimation subtree within the options subtree: `` You can now adjust any of ChartJS's getAnimation settings by using the getters and setters provided in that particular class.

Collections

If ChartJS requires an array with certain items as subsets in a configuration option that array will be represented by a collection in PHPChartJS. The collection can always by accessed directly to add, remove and replace values.

In some cases a specific object with a predetermined list of options is required in a collection. In these cases methods will be provided to create a new instance of said object and adding it to the collection.

Datasets are stored in a collection:

``

But the actual data in a dataset is also stored inside a collection:

Installation

Using composer

$ composer require halfpastfouram/phpchartjs

Development

This project uses composer, which should be installed on your system. Most Linux systems have composer available in their PHP packages. Alternatively you can download composer from getcomposer.org.

If you use the PhpStorm IDE then you can simply init composer through the IDE. However, full use requires the commandline. See PhpStorm help, search for composer.

To start development, do composer install from the project directory.

Remark Do not use composer update unless you changed the dependency requirements in composer.json. The difference is that composer install will use composer.lock read-only, while composer update will update your composer.lock file regardless of any change. As the composer.lock file is committed to the repo, other developers might conclude dependencies have changed, while they have not.
