how to foreach datasets in chartjs laravel - laravel

Question

I have a problem that I can't loop datasets chartjs in laravel.
below is my code in model
public function umur($tanggal)
{
return DB::table('riwayat')
->select('umur')
->where('tanggal_riwayat', $tanggal)
->groupBy('umur')
->get();
}
public function data_grafik($tanggal, $umur)
{
return DB::table('riwayat')
->select('hasil_keputusan', DB::raw('COUNT(id_riwayat) as jml_riwayat'))
->where('tanggal_riwayat', $tanggal)
->where('umur', $umur)
->groupBy('hasil_keputusan')
->get();
}
this is my controller
$tanggal="2022-08-10";
$query = $this->m_dashboard->grafik($tanggal);
$dataa = [];
foreach ($query as $row) {
$dataa['label'][] = $row->umur;
$data_grafik=$this->m_dashboard->data_grafik($tanggal, $row->umur);
foreach ($data_grafik as $value) {
$dataa['label_1'][] = $value->hasil_keputusan;
$dataa['jml_riwayat'][] = $value->jml_riwayat;
}
}
$data = [
'chart_data' => json_encode($dataa),
];
return view('admin.dashboard', $data);
this is my view
var cData = JSON.parse('<?php echo $chart_data; ?>');
const labels = cData.label;
const data = {
labels: labels,
datasets: [{
label: cData.label_1,
backgroundColor: 'rgb(255, 99, 132)',
borderColor: 'rgb(255, 99, 132)',
data: cData.jml_riwayat,
}
]
};
const config = {
type: 'bar',
data: data,
options: {}
};
const myChart = new Chart(
document.getElementById('myChart'),
config
);
this is my output
and this is the ouput what I want
Thanks in advance and sorry for occasional english mistakes
