Charts doesn't appear

Question

I trying to use Chart.js in my web, but the chart won't appear and there's no error code in chrome console. I'm using Chart.js v2.7.2.

I tried any solution but doesn't help me, i also copy the code from chart.js documentation. what's wrong?

 var ctx = document.getElementById("myChart").getContext('2d'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: ["Red", "Blue"], datasets: [{ label: '# of Votes', data: [12, 19], backgroundColor: [ 'rgba(255, 99, 132, 0.2)', 'rgba(54, 162, 235, 0.2)' ], borderColor: [ 'rgba(255,99,132,1)', 'rgba(54, 162, 235, 1)' ], borderWidth: 1 }] }, options: { scales: { yAxes: [{ ticks: { beginAtZero:true } }] } } });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.7.2/Chart.js"></script> <canvas id="myChart" width="400" height="400"></canvas>

Try this:

<html>
<head>
<script type="text/javascript">
window.onload = function () {

var chart = new CanvasJS.Chart("chartContainer", {
    theme: "light1", // "light2", "dark1", "dark2"
    animationEnabled: false, // change to true      
    title:{
        text: "Basic Column Chart"
    },
    data: [
    {
        // Change type to "bar", "area", "spline", "pie",etc.
        type: "column",
        dataPoints: [
            { label: "apple",  y: 10  },
            { label: "orange", y: 15  },
            { label: "banana", y: 25  },
            { label: "mango",  y: 30  },
            { label: "grape",  y: 28  }
        ]
    }
    ]
});
chart.render();

}
</script>
</head>
<body>
<div id="chartContainer" style="height: 370px; width: 100%;"></div>
