d3js /环氧of无法读取未定义的属性“长度”
提问于 2017-01-19 10:33:09
我真的搞不懂这里出了什么问题。我试图用JSON-数据绘制一个划时代的线条图。
JSON格式化程序和Validator说它是有效的JSON。
Epoch/D3不呈现图表，而是在控制台中的d3.js中得到一个"Uncaught :无法读取未定义的属性‘长度’“。
我尝试了不同版本的d3，最新版本和v3.5.17版本，如本文所述：https://github.com/epochjs/epoch/issues/226
这是我的代码：
<html>
<head>
<link rel="stylesheet" href="css/epoch.min.css" type="text/css">
<script src="js/jquery-3.1.1.min.js"></script>
<script src="js/d3.js"></script>
<script src="js/epoch.js"></script>
</head>
<body>
<div id="linechart" class="epoch category20" style="width: 700px; height: 250px"></div>
<script type="text/javascript">
$('#linechart').epoch({
type: 'line',
axes: ['left', 'right', 'bottom'],
data: [{"label":"LabelA","value":[{"x":1,"y":7163960},{"x":2,"y":7163960},{"x":3,"y":7164484},{"x":4,"y":7164572},{"x":5,"y":7164908},{"x":6,"y":7167360},{"x":7,"y":7176940},{"x":8,"y":7176880},{"x":9,"y":7176880},{"x":1,"y":7209696},{"x":11,"y":7260416},{"x":12,"y":7287716},{"x":13,"y":7288548},{"x":14,"y":7289324},{"x":15,"y":7289324}]},{"label":"LabelB","value":[{"x":1,"y":2312004},{"x":2,"y":2311828},{"x":3,"y":2373860},{"x":4,"y":2768644},{"x":5,"y":2620956},{"x":6,"y":2705648},{"x":7,"y":2689684},{"x":8,"y":2360368},{"x":9,"y":2360376},{"x":1,"y":2603128},{"x":11,"y":2705996},{"x":12,"y":2830920},{"x":13,"y":2442880},{"x":14,"y":2407872},{"x":15,"y":2386400}]},{"label":"LabelC","value":[{"x":1,"y":2312004},{"x":2,"y":2311828},{"x":3,"y":2373860},{"x":4,"y":2768644},{"x":5,"y":2620956},{"x":6,"y":2705648},{"x":7,"y":2689684},{"x":8,"y":2360368},{"x":9,"y":2360376},{"x":1,"y":2603128},{"x":11,"y":2705996},{"x":12,"y":2830920},{"x":13,"y":2442880},{"x":14,"y":2407872},{"x":15,"y":2386400}]}]
});
