一实战

1 Django_lab\urls.py

# -*- coding: utf-8 -*-

from django.conf.urls import url,include
from django.contrib import admin

urlpatterns = [
url(r'^admin/', admin.site.urls),
# 定义图表url
url(r'^chart/', include('chart.urls')),
]

2 在settings.py中添加图表应用

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
# 图表应用
'chart',
]

3 chart\urls.py

# -*- coding: utf-8 -*-
from django.conf.urls import url,include
from . import views
urlpatterns = [
# 折线图的url
url(r'^linediagram/$', views.showlinediagram),
]

4 views.py

# -*- coding: utf-8 -*-
from django.shortcuts import render
from django.http import HttpResponse

from matplotlib.figure import Figure
from matplotlib.backends.backend_agg import FigureCanvasAgg
from matplotlib.dates import DateFormatter
import matplotlib.pyplot as plt

import random
import datetime

# 折线图对应的的模板
def showlinediagram(request):
return render(request, 'chart/showlinediagram.html')

5 模板showlinediagram.html

<html>
<head>
<meta charset="UTF-8" />
<title>Highcharts 教程 | 菜鸟教程(runoob.com)</title>
<script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
</head>
<body>
<div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div>
<script language="JavaScript">
$(document).ready(function() {
var title = {
text: '月平均气温'
};
var subtitle = {
text: 'Source: runoob.com'
};
var xAxis = {
categories: ['一月', '二月', '三月', '四月', '五月', '六月'
,'七月', '八月', '九月', '十月', '十一月', '十二月']
};
var yAxis = {
title: {
text: 'Temperature (\xB0C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
};

var tooltip = {
valueSuffix: '\xB0C'
}

var legend = {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
};

var series = [
{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
26.5, 23.3, 18.3, 13.9, 9.6]
},
{
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8,
24.1, 20.1, 14.1, 8.6, 2.5]
},
{
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6,
17.9, 14.3, 9.0, 3.9, 1.0]
},
{
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0,
16.6, 14.2, 10.3, 6.6, 4.8]
}
];

var json = {};

json.title = title;
json.subtitle = subtitle;
json.xAxis = xAxis;
json.yAxis = yAxis;
json.tooltip = tooltip;
json.legend = legend;
json.series = series;

$('#container').highcharts(json);
});
</script>
</body>
</html>
