Django使用可视化包Pyechart

Echarts 是百度开源的一个数据可视化 JS 库，主要用于数据可视化。pyecharts 是一个用于生成 Echarts 图表的类库。实际上就是 Echarts 与 Python 的对接。本次使用django2.0 和 pyecharts0.3.3

1. setttins.py 添加自己创建的app名称，和静态文件的路径

INSTALLED_APPS = [

'django.contrib.admin',

'django.contrib.auth',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.messages',

'django.contrib.staticfiles',

'my_report',

]

DATABASES = {

'default': {

'ENGINE': 'django.db.backends.oracle',

'NAME': 'devdb',

'USER': 'root',

'PASSWORD': '654321',

'HOST': '127.0.0.1',

'PORT': '3306',

}

STATIC_URL = '/static/'

STATICFILES_DIRS = (

os.path.join(BASE_DIR, 'static'),

)

2.urls.py

from django.contrib import admin

from django.urls import path

from month_report import views

urlpatterns = [

path('admin/', admin.site.urls),

path('guo/', views.guo_report, name='index'),

]

3.views.py

from django.shortcuts import render

from django.db import connection

from django.http import HttpResponse

from django.template import loader

from pyecharts import Bar, Geo

def exc_sql(sql):

cursor = connection.cursor()

cursor.execute(sql)

result = cursor.fetchall()

return result

def guo_report(request):

# select province, difi_re_num from REPORT_REG

ret = """select city, difi_re_num from REPORT_REG a, province_to_city b where a.province=b.province"""

data_list = exc_sql(ret)

attr = [i[0] for i in data_list]

value = [i[1] for i in data_list]

geo = Geo("全国各地用户注册图", width=1200, height=600)

geo.add("各省注册量", attr, value, type="effectScatter", border_color="#ffffff", symbol_size=2,

is_label_show=True, label_text_color="#00FF00", label_pos="inside", symbol_color="yellow",

geo_normal_color="#006edd", geo_emphasis_color="#0000ff")

data = {'data': geo.render_embed()}

return render(request, 'guo_report.html', data)
