Scatter Highcharts responsive issue Yii2

Question

I am using scatter chart in Yii2 using the following extension https://github.com/miloschuman/yii2-highcharts

For responsive I have passed parameters like this.

<?php 
use miloschuman\highcharts\Highcharts; 
echo Highcharts::widget([               
    'options' => [
          'responsive' => [
            'rules'=> [
                [
                    'condition'=>
                    [
                        'maxWidth' => 500,
                    ],
                    'chartOptions'=> [
                        'legend' => [
                            'enabled'=> true,
                            'align'=> 'center',
                            'verticalAlign'=> 'bottom',
                            'layout'=> 'horizontal',
                        ],
                    ],
                ]
            ],                                
        ], 

    ]); 
?>

But its not working for mobile as well as tablet.Can any one have idea? Thanks!
