does sum (total) value not appear on the chart?

$abc = kehadiran::select(DB::raw('sum(total) as sums'), DB::raw("DATE_FORMAT(day,'%M %Y') as months"))->groupBy('months')->get();

  $chart = Charts::database($abc, 'bar', 'highcharts')->title("Kehadiran Jemaat Perbulan")->elementLabel("Total")->dimensions(1000, 500)->responsive(false)->groupBy('months'); 
return view('chart',compact('chart'));

the result is always one, I hope the addition is raw
