Laravel Image Charts

Image-charts PHP library to generate charts in image format for your Laravel application.

Installation

You can install the package via Composer:

composer require mohsen-mhm/laravel-image-charts

Publish the Configuration File

To publish the configuration file, use the following command:

php artisan vendor:publish --provider="MohsenMhm\LaravelImageCharts\Providers\ImageChartsServiceProvider" --tag="config"

This will create a configuration file named image-charts.php in the config directory.

---

Configuration

You can configure the package settings in the config/image-charts.php file. The default configuration values are:

return [
    'base_url' => env('IMAGE_CHARTS_BASE_URL', 'https://image-charts.com/chart.js/2.8.0'),
    'default_bg_color' => '#2B2B2B',
    'default_dataset_bg_color' => '#FCBB3D',
    'default_dataset_border_color' => '#FCBB3D',
    'default_width' => '900',
    'default_height' => '600',
    'default_title_text' => 'mohsen.sbs',
    'default_image_path' => storage_path('app/public/charts'),
];

Usage

Generating a Chart URL

Here's an example of how to use the package to generate a chart URL:

use MohsenMhm\LaravelImageCharts\ImageChart;

$chartUrl = (new ImageChart())
        ->setData([10, 20, 30])
        ->setLabels(['January', 'February', 'March'])
        ->getUrl();

or use Facade:

use MohsenMhm\LaravelImageCharts\Facades\ImageChartFacade as ImageChart;

$chartUrl = ImageChart::setData([10, 20, 30])
        ->setLabels(['January', 'February', 'March'])
        ->getUrl();

You can then use this URL to display the chart in your application.

<img src="{{ $chartUrl }}" alt="Chart">

Downloading the Chart Image

You can also download the generated chart image to a local file. If no path is specified, the image will be saved to the default path specified in the configuration file.

use MohsenMhm\LaravelImageCharts\ImageChart;

$fullImagePath = (new ImageChart())
        ->setData([10, 20, 30])
        ->setLabels(['January', 'February', 'March'])
        ->getImage();

or use Facade:

use MohsenMhm\LaravelImageCharts\Facades\ImageChartFacade as ImageChart;

$fullImagePath = ImageChart::setData([10, 20, 30])
        ->setLabels(['January', 'February', 'March'])
        ->getImage();

This will save the image to the default path with a generated file name and return the full path to the saved image. You can also specify a custom path:

use MohsenMhm\LaravelImageCharts\ImageChart;

$customPath = storage_path('app/public/custom_charts');

$fullImagePath = (new ImageChart())
        ->setData([10, 20, 30])
        ->setLabels(['January', 'February', 'March'])
        ->getImage($customPath);

or use Facade:

use MohsenMhm\LaravelImageCharts\Facades\ImageChartFacade as ImageChart;

$customPath = storage_path('app/public/custom_charts');

$fullImagePath = ImageChart::setData([10, 20, 30])
        ->setLabels(['January', 'February', 'March'])
        ->getImage($customPath);

Output

Full Usage Example

use MohsenMhm\LaravelImageCharts\ImageChart;

try {
    $imageChart = (new ImageChart())
        ->setLabels(['January', 'February', 'March'])
        ->setData([10, 20, 30])
        ->setBackgroundColor('#FFFFFF')

        ->setWidth('800')
        ->setHeight('400')
        ->setTitleText('Monthly Data');

    $chartUrl = $imageChart->getUrl();
    $imagePath = $imageChart->getImage();
    $binaryData = $imageChart->getBinary();

    echo "Chart URL: $chartUrl\n";
    echo "Image saved at: $imagePath\n";
    echo "image in binary format: $binaryData\n";
} catch (InvalidArgumentException $e) {
    echo 'Error: ' . $e->getMessage();
}

Output

Chart URL: https://image-charts.com/chart.js/2.8.0 ...
