What is Larapex Chart ?

Larapex chart is a library to add beautiful charts for blade. It’s a laravel wrapper of Apex chart library. Larapex chart allow you to generate chart writting with php.

How to use it ?

To use it add Larapex chart with composer to your project

composer require arielmejiadev/larapex-charts

Then publish config file with this command

php artisan vendor:publish --tag=larapex-charts-config

with this, the setup is done ! And you can start to use Larapex Chart ! 🙂

Chart example

To create chart use this command :

php artisan make:chart MonthlyUsersChart

Then select a chart type :

- [x] Pie Chart
- [ ] Donut Chart
- [ ] Radial Bar Chart
- [ ] Polar Area Chart
- [ ] Line Chart
- [ ] Area Chart
- [ ] Bar Chart
- [ ] Horizontal Bar Chart
- [ ] HeatMap Chart
- [ ] Radar Chart

Now you have a new file with the chart in app/Charts/MonthlyUsersChart.php

<?php

namespace App\Charts;

use ArielMejiaDev\LarapexCharts\LarapexChart;

class MonthlyUsersChart
{
    protected $chart;

    public function __construct(LarapexChart $chart)
    {
        $this->chart = $chart;
    } 

    public function build()
    {
        return $this->chart->pieChart()
            ->setTitle('Top 3 scorers of the team.')
            ->setSubtitle('Season 2021.')
            ->addData([40, 50, 30])
            ->setLabels(['Player 7', 'Player 10', 'Player 9']);
    }
}

now in your controller you inject the chart object :

public function index(MonthlyUsersChart $chart)
{
    return view('users.index', ['chart' => $chart->build()]);
}

And to finish add $chart->container(), $chart->cdn() and $chart->script() methods in the view to render a chart
