        ]
    },

// ...

StoreChartImage::make()->handle([
    'title' => [
        'text' => 'Basic Bar Chart',
    ],
    'xAxis' => [
        'type' => 'category',
        'data' => ['Shirts', 'Cardigans', 'Chiffons', 'Pants', 'Heels', 'Socks'],
    ],
    'yAxis' => [

            'data' => [5, 20, 36, 10, 10, 20],
        ],
    ],
]);

Overwrite the default attributes from config file:

$action = StoreChartImage::make()
    ->baseOptionPath(resource_path('echarts/base-option.mjs')) // base chart to be merged
    ->mimeType(MimeTypes::PNG) // PNG, JPG, PDF, SVG
    ->optimize(true) // optimize with pngcrush
    ->filePath('app/public') // storage path
    ->fileName('simple-bar-chart') // w/o extension
    ->width(600) // image width
    ->height(600); // image height


$action->handle(options: [...]);
