I want the sum field (total) monthly, but the sum value cannot appear on the chart (consoleTv / 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')); }
