My blade file code is:
@foreach ($radio_data as $data)
<div style="text-align: center" class="row">
<div class="col-md-4 text-center" >
<canvas id="myChart"></canvas>
</div>
</div>
@php array_push($dataPoints, array("label"=> " $data->answer ", "y"=> $data->num )); @endphp
<p>{{ $data->answer }}: {{ $data->num }}</p>
@endforeach
I am fetching data in controller and send it to view.
Finally I did this with dynamic canvas id and update function. Here is my code:
<div style="text-align: center" class="row">
<div class="col-md-4 text-center" >
<canvas id="{{ $loop->index }}"></canvas>
</div>
</div>
<script>
let {{ 'c'.$u }} = new Chart(document.getElementById({{ $loop->index }}), {
type: 'pie',
data: {
labels: [],
datasets: [{
label: '# of Votes',
data: [],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255, 99, 132, 1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
}
}
});
</script>
@foreach ($radio_data as $data)
<script> {{ 'c'.$u }}.data.labels.push('{{ $data->answer }}'); {{ 'c'.$u }}.data.datasets.forEach((dataset) => {
dataset.data.push({{ $data->num }});
});
{{ 'c'.$u }}.update(); </script>
