Set labels from array - symfony

Question

I'm starting with chartjs and i'm already struggling. I want to set my labels with data I get from a query :
public function find4Chart($joueur){
$qb = $this->createQueryBuilder('p');
$qb->join('p.partie','y')
->join('y.game','g')
->select('g.name')
->addSelect('COUNT(p) AS sumParties')
->where('p.joueur = :joueur')
->setParameter('joueur', $joueur)
->groupBY('g.name');
$query = $qb->getQuery();
return $query->getResult();
}
Then I set up the chart like this :
var ctx = document.getElementById('myChart');
var myChart = new Chart(ctx, {
type: 'doughnut',
data: {
labels: [{{ chart.name }}],
But it gives me the following error and I don't know why or what to do here :/
Key "name" for array with keys "0, 1" does not exist.
Thx !

Regarding your own answer - you could change this part:
$arrChart = array();
foreach($chart as $c){
$name = $c['name'];
array_push($arrChart, $name);
}
into this:
$arrChart = array_column($chart, 'name');
You can read more about array_column here

Ok it worked for me this way :
public function show(Joueur $joueur): Response
{
$em = $this->getDoctrine()->getManager();
$chart = $em->getRepository(Played::class)->find4Chart($joueur);
$arrChart = array();
foreach($chart as $c){
$name = $c['name'];
array_push($arrChart, $name);
}
return $this->render('joueur/show.html.twig', [
'joueur' => $joueur,
'chart' => $arrChart,
]);
}
Chart :
var ctx = document.getElementById('myChart');
var myChart = new Chart(ctx, {
type: 'doughnut',
data: {
labels: {{chart | json_encode | raw}},
I don't know if it's the right way to do it but it works, if any of you have a better idea, I'll take it ;)
