Add function to return datasets for the next ajax request to update data in the graph.

@mitulkoradiya thanks for the contribution!

But I don't really understand the use-case. What do you mean by "next ajax request", can you provide the code example of how you would use such a method?

The graph data is updated on filter change

1. Backend Ajax request code

   
   ...
   $options = [
   'chart_title' => 'Company',
   'chart_type' => 'line',
   'report_type' => 'group_by_date',
   'model' => Item::class,
   'group_by_field' => 'created_at',
   'group_by_period' => $filter,
   'filter_days' => 50,
   'chart_color' => '160,208,245'
   ];

$companyChart = new LaravelChart($options); return response()->json($companyChart->getDatasets()); ...

2. Front-end javascript code

{!! $companyChart->renderChartJsLibrary() !!} {!! $companyChart->renderJs() !!}

@mitulkoradiya I've never seen anyone using this package like this, but ok, fair enough, it doesn't break anything, so I will merge the change.
