以下是代码

首先创建项目项目、应用、在settings中注册

diango-admin startproject pyecharts_django_demo
cd pyecharts_django_demo
python manage.py startapp demo

按照官网说的在demo文件夹下新建templates文件夹，复制模板文件到这个目录下配置路由

### pyecharts_django_demo目录下的url文件
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('demo/',include('demo.urls',namespace='demo')),
]

### demo目录下的urls
from django.urls import path
from . import views

app_name = 'demo'

urlpatterns = [
    path('',views.index,name='index'),
]

视图函数

from django.shortcuts import render

from jinja2 import Environment, FileSystemLoader
from pyecharts.globals import CurrentConfig
from django.http import HttpResponse

CurrentConfig.GLOBAL_ENV = Environment(loader=FileSystemLoader("./demo/templates"))

from pyecharts import options as opts
from pyecharts.charts import Bar, Map
from pyecharts.faker import Faker


# Create your views here.

def index(request):
    bar_plot = (
        Bar()
        .add_xaxis(["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"])
        .add_yaxis("商家A", [5, 20, 36, 10, 75, 90])
        .add_yaxis("商家B", [15, 25, 16, 55, 48, 8])
        .set_global_opts(title_opts=opts.TitleOpts(title="Bar-基本示例", subtitle="我是副标题"))
    )
    bar_plot = bar_plot.render_embed()
    world_map = (
    Map()
    .add("", [list(z) for z in zip(Faker.country, Faker.values())], "world",is_map_symbol_show=False,is_roam=False)
    .set_series_opts(label_opts=opts.LabelOpts(is_show=False))
    .set_global_opts(
        title_opts=opts.TitleOpts(title="Map-世界地图"),
        visualmap_opts=opts.VisualMapOpts(max_=200))
    )
    world_map = world_map.render_embed()
    context = {'bar_plot':bar_plot,'world_map':world_map}
    return render(request,'demo/index.html',context=context)
