Chart.js problem with applying

Hi to averyone. Today i have a problem with Chart.js. When i paste the code to a <head> tag and </body> tag sections on a page settings all is working. I can see the chart, BUT i can`t really make this chart fit to any div block or section, because the chart shows on the whole screen area. Nothing i made was
successful. I Really need a help with this…

Code:

<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.4.0/Chart.min.js"></script>
<canvas id="myChart" width="100" height="100"></canvas>
<script>
var ctx = document.getElementById("myChart").getContext('2d');
var myChart = new Chart(ctx, {
    type: 'radar',
    data: {
        labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2, 3],
            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: {
            yAxes: [{
                ticks: {
                    beginAtZero:true
                }
            }]
        }
    }
});
</script>
</head>

<body>
<div id="myChart" style="height: 5px; width: 10px;"></div>
  <script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
</body>

And for the div blocks i always used “myChart” id for that code. Nothing help.
