How to plot a canvasJS graph in canvas tag?

I have tried to plot the canvasJS graph in the canvas tag of HTML so I'm not able to do so I need some help..!

<html>
    <head>
        <script>
            window.onload = function () {

            var options = {
                title: {
                    text: "Desktop OS Market Share in 2017"
                },
                data: [{
                    type: "pie",
                    dataPoints: [
                        { y: 48.36, label: "Windows 7" },
                        { y: 26.85, label: "Windows 10" },
                        { y: 1.49, label: "Windows 8" },
                        { y: 6.98, label: "Windows XP" },
                        { y: 6.53, label: "Windows 8.1" },
                        { y: 2.45, label: "Linux" },
                        { y: 3.32, label: "Mac OS X 10.12" },
                        { y: 4.03, label: "Others" }
                    ]
                }]
            };
            $("#chartContainer").CanvasJSChart(options);

            }
        </script>
    </head>
    <body>
        <div>
            <canvas id="chartContainer" height="300" width="400"> </canvas>
        </div>
        <script src="https://canvasjs.com/assets/script/jquery-1.11.1.min.js"></script>
        <script src="https://canvasjs.com/assets/script/jquery.canvasjs.min.js"></script>
    </body>
</html>

I want the graph to be plotted using the canvas tag but not by using div tag. Because once I use this code in the bootstrap template it comes out the panel allotted for the graph.

Solution

CanvasJS dynamically creates and adds Canvas to the chartContainer(div) provided. Changing canvas to div should work fine in your case. Please find the updated code below:

var options = {
    title: {
        text: "Desktop OS Market Share in 2017"
    },
    data: [{
        type: "pie",
        dataPoints: [
            { y: 48.36, label: "Windows 7" },
            { y: 26.85, label: "Windows 10" },
            { y: 1.49, label: "Windows 8" },
            { y: 6.98, label: "Windows XP" },
            { y: 6.53, label: "Windows 8.1" },
            { y: 2.45, label: "Linux" },
            { y: 3.32, label: "Mac OS X 10.12" },
            { y: 4.03, label: "Others" }
        ]
    }]
};
$("#chartContainer").CanvasJSChart(options);
