Laravel Chart需要连接数据库

I am developing Training Management system so that it has a data table called registerdetails and it consist a data attribute called trainee_division, so that consist few several divisions and there are trainees who are in under those divisions. here is the few divisions INOC, INFRA, Implementation, RAN so what i need is draw a bar chart on x axis using division names on y axis total count a division.

Here is the incomplete controller

public function division_details()
{

  $chart = Charts::multi('bar', 'chartjs')

        ->title("Trainee Divisions")
        ->dimensions(0, 500) 
        ->template("material")
        ->dataset('Trainee', [5,20,100])
        ->labels(['OPERATIONAL', 'INOC', 'Three'])
        ->responsive(false)
        ->Width(0);

    return view('registeredusers.divisiondetails', ['chart' => $chart]);
}

Here is the view for that

`<div class="panel panel-default">
<div class="col-md-6 col-md-offset-3">

            <div class="panel-body">

            {!! $chart->render() !!}
        </div>
        </div>
        </div>`

Here is the relevant route.

Route::get('DivisionDetails', 'UserRegisterController@division_details');

These are the packages um using .

provider as 

`Maatwebsite\Excel\ExcelServiceProvider::class,'

aliases as

'Excel' => Maatwebsite\Excel\Facades\Excel::class,

Can anyone help me to fix this problem.
