## 1.python环境安装
## 2.python开发工具PyCharm安装
在terminal下输入命令安装:
可以先使用pip list查看已安装的模块
PS D:\date\PyCharm\djangoProject> pip list
继续使用pip install django命令安装django模块
PS D:\date\PyCharm\djangoProject> pip install django
# 创建项目目录
PS D:\date\PyCharm\djangoProject>django-admin startproject www
# 打开项目目录
PS D:\date\PyCharm\djangoProject>cd www
导入echarts.min.js 和 jquery-2.2.4.js文件
创建index.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document01</title>
<style>
.box{
width: 300px;
height: 300px;
background-color: rgb(188, 227, 236);
}
</style>
</head>
<body>
<!-- 2.准备具有大小的DOM容器 -->
<div class="box"></div>
<script type="text/javascript" src="static/jquery-2.2.4.js"></script>
<script type="text/javascript" src="static/echarts.min.js"></script>
<script>
//3.初始化实例对象 echarts.init(dom容器)
var myChart = echarts.init(document.querySelector(".box"));
//4.指定配置项和数据
var option = {
// 标题组件
title: {
text: 'ECharts 入门示例'
},
// 提示框组件
tooltip: {},
//图例组件
legend: {
data:['销量']
},
// 直角坐标系grid中的x轴
// -boundaryGap:坐标轴两边留白策略true,这时候刻度只是作为分割线,标签和数据点都会在两个刻度之间带(band)中间
xAxis: {
data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
},
// 直角坐标系grid的y轴
yAxis: {},
// 系列列表,每个系列通过type决定自己的图标类型
// 通俗的理解:图标数据,通过什么类型的图标,可以多个图标重叠
series: [{
name: '销量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}]
// grid:直角坐标系内绘图网格
// color:调色盘颜色列表
// stack:数据堆叠,同个类目轴上系列配置相同的stack值后,后一个系列的值会在前一个系列的值上相加
};
//5.将配置项设置给echarts实例对象,使用刚指定的配置项和数据显示图表。
myChart.setOption(option);
</script>
</body>

from django.shortcuts import render
'''调用HTML模版'''
def index(request):
title = "漏刻有时数据可视化-主线图"
return render(request, 'index.html', {"name": title})
'''导入视图'''
from django.urls import path
from . import views
'''配置url规则'''
urlpatterns = [
path('', views.index),
]
修改以下内容:模版文件路径配置
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')], # 修改目录位置
'APP_DIRS': True,
'OPTIONS': {

'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
修改以下内容:静态文件路径配置
# 配置静态文件路径;
STATIC_URL = '/static/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]

例如我们想使用这个模板
点进去后,复制左边的代码
只需替换index.html中option的代码块就可以
