我发现 nvd3 用于创建图表，我喜欢Line plus bar chart。但我什至不能让他们的例子奏效。我在哪里做错了？我已经尝试在示例页面上包含几乎所有的 js 脚本（上面的链接）。这是我的python代码：

<!DOCTYPE html>
<head>
<meta charset="utf-8">
{% load staticfiles %}
    <style>
        #chart svg {
            height: 400px;
        }
    </style>

<link href="{% static "css/nv.d3.css" %}" rel="stylesheet">

<script src="{% static "js/d3.v3/d3.v3.min.js" %}"></script>
<script src="{% static "js/d3.v3/d3.v3.js" %}"></script>
<script src="{% static "js/d3.v3/fisheye.js" %}"></script>
<script type="text/javascript" src="{% static "js/graph/linePlusBar.js" %}"></script>
</head>

<body>
<div id="chart">
    <svg> </svg>
</div>

<h1>{{ stock.name }} dividend history</h1>
<ul>
{% for dividend in stock.dividend_set.all %}
    <li>{{ dividend.date}} - {{dividend.amount}}</li>
{% endfor %}
</ul>
</body>
</html>

这是加载页面的 html 输出

<!DOCTYPE html>
<head>
<meta charset="utf-8">

    <style>
        #chart svg {
            height: 400px;
        }
    </style>

<link href="/static/css/nv.d3.css" rel="stylesheet">

<script src="/static/js/d3.v3/d3.v3.min.js"></script>
<script src="/static/js/d3.v3/d3.v3.js"></script>
<script src="/static/js/d3.v3/fisheye.js"></script>
<script type="text/javascript" src="/static/js/graph/linePlusBar.js"></script>
</head>

<body>
<div id="chart">
    <svg> </svg>
</div>

<h1>Agilent Technolog dividend history</h1>
<ul>

    <li>Nov. 1, 2006 - 2.057</li>

    <li>March 30, 2012 - 0.1</li>

    <li>June 29, 2012 - 0.1</li>

    <li>Sept. 28, 2012 - 0.1</li>

    <li>Dec. 27, 2012 - 0.1</li>

    <li>March 28, 2013 - 0.12</li>

</ul>
</body>
</html>

并且默认 linePlusBar.js

nv.addGraph(function() {
    var testdata = exampleData(),
        chart = nv.models.linePlusBarChart()
            .margin({top: 30, right: 60, bottom: 50, left: 70})
            .x(function(d,i) { return i })
            .color(d3.scale.category10().range());

    chart.xAxis.tickFormat(function(d) {
        var dx = testdata[0].values[d] && testdata[0].values[d].x || 0;
        return d3.time.format('%x')(new Date(dx))
    });

    chart.y1Axis
        .tickFormat(d3.format(',f'));

    chart.y2Axis
        .tickFormat(function(d) { return '$' + d3.format(',f')(d) });

    chart.bars.forceY([0]);
    //chart.lines.forceY([0]);

    d3.select('#chart svg')
        .datum(exampleData())
        .transition().duration(500).call(chart);

    nv.utils.windowResize(chart.update);

    return chart;
});



function exampleData() {
    return [

我错过了什么？svg 在我的 html 页面上是空白的。感谢您的帮助，我真的迷失在这个微不足道的事情上。

如果您使用 Python 和 NVD3，您可能需要查看 python-nvd3： https ://github.com/areski/python-nvd3

我们还在开发 django 包装器： https ://github.com/areski/django-nvd3

看起来您还没有将 NVD3 库添加到您的项目中。你可以从这里得到它。

在我的机器上使用 nvd3 javascript 库测试了您的代码，它工作正常。对我来说看起来像这样。 在此处输入图像描述
