Solution from @Aless55 works perfectly fine 来自@Aless55 的解决方案完美无缺
<script>
window.onload = function () {
var chart = new CanvasJS.Chart("chartContainer", {
animationEnabled: true,
theme: "light2",
title:{
text: "Simple Line Chart"
},
data: [{
type: "line",
indexLabelFontSize: 16,
dataPoints: [
@foreach($records as $prc)
{ y: {{$prc->price}} },
@endforeach
]
}]
});
chart.render();
}
</script>
Try this piece:试试这个:
<script>
window.onload = function () {
var records = "<?php echo $records ?>"
var data = records.map((function (record) {
return {y: record.price}
}))
var chart = new CanvasJS.Chart("chartContainer", {
animationEnabled: true,
theme: "light2",
title:{
text: "Simple Line Chart"
},
data: [{
type: "line",
indexLabelFontSize: 16,
dataPoints: data
}]
});
chart.render();
}
</script>
