django可视化图表

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
