README

Create chart widgets using Google Charts.

Installation

You can install the package into a Laravel app that uses Filament via composer::

composer require arbermustafa/filament-google-charts-widgets

Filament V2 - if you are using Filament v2.x, you can use this section

You can publish the config file with:

php artisan vendor:publish --tag=filament-google-charts-widgets-config

The config file contains default global customization options for better charts rendering in light/dark theme based on the great work of Weekdone

Optionally, you can publish the view using:

php artisan vendor:publish --tag=filament-google-charts-widgets-views

Usage

Pie chart

use ArberMustafa\FilamentGoogleCharts\Widgets\PieChartWidget;

class DemoPieChart extends PieChartWidget
{
    protected static ?int $sort = 1;

    protected static ?array $options = [
        'legend' => [
            'position' => 'top',
            'alignment' => 'center',
        ],
        'height' => 400,
        'is3D' => false,
    ];

    protected function getHeading(): string
    {
        return 'Pie chart';
    }

    protected function getData(): array
    {
        return [
            ['Label', 'Aggregate'],
            ['Col1', 7.2],
            ['Col2', 23.7],
            ['Col3', 11.1],
        ];
    }
}

Donut chart

use ArberMustafa\FilamentGoogleCharts\Widgets\DonutChartWidget;

class DemoDonutChart extends DonutChartWidget
{
    protected static ?string $heading = 'Donut chart';

    protected static ?int $sort = 2;

    protected static ?float $pieHole = 0.5;

    protected static ?array $options = [
        'legend' => [
            'position' => 'top',
        ],
        'height' => 400,
    ];

    protected function getData(): array
    {
        return [
            ['Label', 'Aggregate'],
            ['Col1', 17.2],
            ['Col2', 23.7],
            ['Col3', 11.1],
        ];
    }
}

Available chart types

Below is a list of available chart widget classes which you may extend, and their corresponding Google Charts documentation page, for inspiration what to return from getData():

• ArberMustafa\FilamentGoogleCharts\Widgets\AreaChartWidget - Google Charts documentation
• ArberMustafa\FilamentGoogleCharts\Widgets\BarChartWidget - Google Charts documentation
• ArberMustafa\FilamentGoogleCharts\Widgets\ColumnChartWidget - Google Charts documentation
• ArberMustafa\FilamentGoogleCharts\Widgets\DonutChartWidget - Google Charts documentation
• ArberMustafa\FilamentGoogleCharts\Widgets\LineChartWidget - Google Charts documentation
• ArberMustafa\FilamentGoogleCharts\Widgets\PieChartWidget - Google Charts documentation

Live updating (polling)

By default, chart widgets refresh their data every 5 seconds.

To customize this, you may override the $pollingInterval property on the class to a new interval:

protected static ?string $pollingInterval = '10s';

Alternatively, you may disable polling altogether:

protected static ?string $pollingInterval = null;

Chart configuration options

You may specify an $options variable on the chart class to control the many configuration options that the Google Charts library provides. For instance, you could change the position off the legend for PieChartWidget class and set a custom height:

protected static ?array $options = [
        'legend' => [
            'position' => 'bottom',
        ],
        'height' => 300,
    ];
