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': 'hysh',
'PASSWORD': 'hysh',
'HOST': '192.168.191.3',
'PORT': '1521',
}
}
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)
4.guo_report.html
