Laravel Charts – Chart integration

Laravel Charts is a package that allows developers to easily integrate charting capabilities into Laravel applications. It provides a fluent interface for creating various types of charts using popular JavaScript charting libraries like Chart.js, Google Charts, and Highcharts, making it easy to visualize data in a user-friendly manner.

 

Key Features of Laravel Charts:

1. Multiple Charting Libraries: Supports various libraries like Chart.js, Google Charts, and Highcharts.
2. Easy Integration: Simple installation and setup process.
3. Fluent API: Provides a clean and fluent API for building charts with minimal configuration.
4. Customizable: Allows customization of chart properties to fit your needs.
5. Data Fetching: Integrates seamlessly with Eloquent models to fetch data for charts.

Installation

To get started with Laravel Charts, follow these steps:

1. Require the Package: Install the package via Composer:
   
   composer require consoleTVs/charts

   1	composer require consoleTVs/charts

2. Publish Configuration (optional): You can publish the configuration file using:
   
   php artisan vendor:publish --provider="ConsoleTVs\Charts\ChartsServiceProvider"

   1	php artisan vendor:publish --provider="ConsoleTVs\Charts\ChartsServiceProvider"

3. Install Chart.js (or any preferred charting library): Depending on which library you want to use, you need to install it. For example, to use Chart.js, you can include it via npm or a CDN.

   Using npm:

   npm install chart.js

   1	npm install chart.js

   Using a CDN: You can also include it in your Blade template:

   <script src="https://cdn.jsdelivr.net/npm/chart.js"></script

   1	<script src="https://cdn.jsdelivr.net/npm/chart.js"></script

Creating a Chart

1. Setting Up a Controller: Create a controller to handle the chart data. For example:
   php artisan make:controller ChartController

   1	php artisan make:controller ChartController

2. Building a Chart: In the ChartController, use the Charts facade to create a chart. Here’s an example of creating a simple bar chart:
   namespace App\Http\Controllers; use ConsoleTVs\Charts\Facades\Charts; use App\Models\Post; // Assuming you have a Post model class ChartController extends Controller { public function index() { $chart = Charts::create('bar', 'chartjs') // Type and library ->title('Posts Per Month') ->elementLabel('Number of Posts') ->labels(['January', 'February', 'March', 'April', 'May']) ->values([5, 10, 15, 20, 25]) // Sample data ->responsive(true) ->dimensions(1000, 500) ->draw(); return view('charts.index', compact('chart')); } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

   namespace App\Http\Controllers;   use ConsoleTVs\Charts\Facades\Charts; use App\Models\Post; // Assuming you have a Post model   class ChartController extends Controller {     public function index()     {         $chart = Charts::create('bar', 'chartjs') // Type and library             ->title('Posts Per Month')             ->elementLabel('Number of Posts')             ->labels(['January', 'February', 'March', 'April', 'May'])             ->values([5, 10, 15, 20, 25]) // Sample data             ->responsive(true)             ->dimensions(1000, 500)             ->draw();           return view('charts.index', compact('chart'));     } }

3. Creating a View: Create a view file at resources/views/charts/index.blade.php to display the chart:
   @extends('layouts.app') @section('content') <div class="container"> <h1>Posts Per Month Chart</h1> <div> {!! $chart->container() !!} </div> </div> {!! $chart->script() !!} @endsection

   1 2 3 4 5 6 7 8 9 10 11 12

   @extends('layouts.app')   @section('content') <div class="container">     <h1>Posts Per Month Chart</h1>     <div>         {!! $chart->container() !!}     </div> </div>   {!! $chart->script() !!} @endsection

4. Defining Routes: Add a route in routes/web.php to access the chart page:
   use App\Http\Controllers\ChartController; Route::get('/charts', [ChartController::class, 'index'])->name('charts.index');

   1 2 3

   use App\Http\Controllers\ChartController;   Route::get('/charts', [ChartController::class, 'index'])->name('charts.index');

    

Customizing Charts

You can customize various aspects of the charts, including colors, tooltips, and legends. Here’s an example of customizing the bar chart further:

 

Using Dynamic Data

You can fetch data dynamically from your Eloquent models. For example, to create a chart showing the number of posts created per month:
