【问题标题】:charts not renderring in django-nvd3图表未在 django-nvd3 中呈现
【发布时间】:2014-03-03 23:17:43
【问题描述】:

我正在尝试将 django-nvd3 与我的 django 项目一起使用,并且正在尝试使折线图示例正常工作。当我的页面加载时,我在 chrome js 控制台中收到以下错误:

未捕获的类型错误:无法设置未定义的属性“monthEnd” nv.d3.js:115(匿名函数) nv.d3.js:115(匿名函数) nv.d3.js:14369 Uncaught TypeError: Object # has no method 'lineChart'(索引):13(匿名函数)(索引):13(匿名 函数)nv.d3.js:63

我基本上已经从这里复制了代码: http://django-nvd3.readthedocs.org/en/latest/classes-doc/line-chart.html

我的看法是:

from django.shortcuts import render_to_response, render
import random
import datetime
import time

def demo_linechart(request):
    """
    lineChart page
    """
    start_time = int(time.mktime(datetime.datetime(2012, 6, 1).timetuple()) * 1000)
    nb_element = 100
    xdata = range(nb_element)
    xdata = map(lambda x: start_time + x * 1000000000, xdata)
    ydata = [i + random.randint(1, 10) for i in range(nb_element)]
    ydata2 = map(lambda x: x * 2, ydata)

    tooltip_date = "%d %b %Y %H:%M:%S %p"
    extra_serie = {"tooltip": {"y_start": "", "y_end": " cal"},
                   "date_format": tooltip_date}
    chartdata = {'x': xdata,
                 'name1': 'series 1', 'y1': ydata, 'extra1': extra_serie,
                 'name2': 'series 2', 'y2': ydata2, 'extra2': extra_serie}
    charttype = "lineChart"

    kw_extra = {
        'x_is_date': True,
        'x_axis_format':"%d %b %Y",
    }

    data = {
        'charttype': charttype,
        'chartdata': chartdata,
        'kw_extra':kw_extra,
    }
    return render(request, 'smcore/nvd3.html', data)

我的 html 是:

{% load static %}

<link rel="stylesheet" type="text/css" href="{% static 'nvd3/nv.d3.css' %}" />
<script type="text/javascript" src='{% static 'smcore/jquery-latest.js' %}'></script>
<script type="text/javascript" src='{% static 'smcore/d3.min.js' %}'></script>
<script type="text/javascript" src='{% static 'nvd3/nv.d3.js' %}'></script>

{% load nvd3_tags %}
<head>
    {% load_chart charttype chartdata "linechart_container" kw_extra %}

    {#    {% load_chart charttype chartdata "linechart_container" True '%d %b %Y %H' %}#}
</head>
<body>
    <h1>Fruits vs Calories</h1>
    {#    {% include_container "piechart_container" 400 500 %}#}
    {% include_container "linechart_container" 400 600 %}

</body>

我的网址是:

url(r'testvis/$', temp.demo_linechart, name='testvis'),

我正在使用 nv.version = '1.1.15b'; d3 = {版本:“2.7.0”}; // semver

请帮忙!!

    【解决方案1】:

    对我来说,解决方案在samesense 这里的第一条评论中:

    https://github.com/areski/django-nvd3/issues/24

    即:

    data = {
        'charttype': charttype,
        'chartdata': chartdata,
        'extra': {'x_is_date': True,
        'x_axis_format': "%d %b %Y %H"},
      }
    Then you fix the template to make it look like the piechart example.
    Change
    {% load_chart charttype chartdata "linechart_container" True "%d %b %Y %H" %}
    to
    {% load_chart charttype chartdata "linechart_container" extra %}
