如何在 canvas 标签中绘制 canvasJS 图表？

Question

我试图在 HTML 的 canvas 标签中绘制 canvasJS 图，所以我做不到，我需要一些帮助..！

<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>

我希望使用 canvas 标签而不是 div 标签绘制图表。因为一旦我在 bootstrap 模板中使用此代码，它就会出现分配给图形的面板。

CanvasJS动态创建并添加Canvas到提供的chartContainer(div)。将 canvas 更改为 div 在您的情况下应该可以正常工作。请在下面找到更新的代码：

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);

<div id="chartContainer" height="300" width="400"></div>
