2. Code implementation

1. Pycharm (Professional Edition) creates a Django project and completes the related configuration
(1) Create a new project with the name echartsdemo1

(2) Create a static directory under the project root directory— >store css, js, img

(3) Attention to configuration setting file

: STATICFILES_DIRS cannot be written wrong

STATIC_URL = '/static/'
STATICFILES_DIRS=[
    os.path.join(BASE_DIR,'static')
]

2. File code:
(1) views.py in the app (model) directory

from django.shortcuts import render
//创建函数echarts
def echarts(request):
    return render(request,'demo.html')

(2) demo.html in the templates directory
(echarts.min.js file can be downloaded from the official website)

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>ECharts</title>
    <!-- 引入 echarts.js 引入静态文件的一种方法-->
    {
    
    % load static %}
    <script src="{% static '/js/echarts.min.js' %}"></script>
</head>
<body>
    <!-- 为ECharts准备一个具备大小（宽高）的Dom -->
    <div id="main" style="width: 600px;height:400px;"></div>
    <script type="text/javascript">
        // 基于准备好的dom，初始化echarts实例
        var myChart = echarts.init(document.getElementById('main'));

        // 指定图表的配置项和数据
        var option = {
    
    
            title: {
    
    
                text: 'ECharts 入门示例'
            },
            tooltip: {
    
    },
            legend: {
    
    
                data:['销量']
            },
            xAxis: {
    
    
                data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
            },
            yAxis: {
    
    },
            series: [{
    
    
                name: '销量',
                type: 'bar',
                data: [5, 20, 36, 10, 10, 20]
            }]
        };

        // 使用刚指定的配置项和数据显示图表。
        myChart.setOption(option);
    </script>
</body>
</html>

(3) urls.py in the echartsdemo1 directory
