只有在Chrome中切换“开发者工具”(F12)时才会显示Javascript图表

THIS QUESTION类似,仅使用不同的图表库(CanvasJS),并且包含我的代码。

图表仅在“开发者工具”之后出现。已经切换(即从开关或开关切换)。

代码I使用:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<meta name="generator" content=
"HTML Tidy for Linux/x86 (vers 25 March 2009), see www.w3.org">
<script type="text/javascript" src="jquery-2.1.3.min.js">
</script>
<script type="text/javascript" src="jquery.canvasjs.min.js">
</script>
<script type="text/javascript">

var dataPoints = [];
(function () {
        $.getJSON('boop.little.json',
                function(thedata) {
                        $.each(thedata, function(i, v) {
                                dataPoints.push({ x: new Date(v.Datetime), y: parseFloat(v.Value) });
                        });
                }
        )
})();

$(function () {
        var options = {
                data: [{
                        type: "splineArea", //change it to column, spline, line, pie, etc
                        dataPoints: dataPoints
                        }
                ]
        };

        $("#chartContainer").CanvasJSChart(options);
});
</script>
<title></title>
</head>
<body>
<div id="chartContainer" style="height: 300px; width: 100%;"></div>
<div id="chartContainer2" style="width:100%; height:300px;"></div>
</body>
</html>

    {
        "Datetime": "01/01/2012 01:50:01",
        "Value": "0.49"
    },
    {
        "Datetime": "01/01/2012 02:00:01",
        "Value": "0.50"
    },
    {
        "Datetime": "01/01/2012 02:10:01",
        "Value": "0.49"
    },
    {
        "Datetime": "01/01/2012 02:20:01",
        "Value": "0.53"
    },
    {
        "Datetime": "01/01/2012 02:30:01",
        "Value": "0.51"
    }
]

有趣的是(以及它出现的原因),删除该行:

<div id="chartContainer2" style="width:100%; height:300px;"></div>

完全停止图表渲染! (即使使用切换开发人员工具)。 这里有些可疑,有人可以建议进一步调试吗?

干杯,

PS。仅供参考:IE9中没有显示任何内容,无论F12切换(预期的IE行为?)。
