Zrender基本案例

参考：https://ecomfe.github.io/zrender-doc/public/api.html

效果：

流程：

引入 zrender 库

编写 div 容器

初始化 zrender 对象

初始化 zrender 绘图对象

调用 zrender add 方法绘图

代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <script src="https://cdn.jsdelivr.net/npm/zrender@4.3.0/dist/zrender.js"></script>
</head>
<body>
    <div id="container" style="width: 800px;height: 800px;"></div>
    <script>
        var zr = zrender.init(document.getElementById('container'));
        var rect = new zrender.Rect({
          shape: {
            x: 0,
            y: 0,
            width: 50,
            height: 50
          },
          style: {
            fill: 'red',
            lineWidth: 0
          }
        });
        var line = new zrender.Polyline({
          shape: {
            points:[
              [100, 100],
              [250, 75],
              [300, 100]
            ]
          },
          style: {
            stroke: 'blue',
            lineWidth: 1
          }
        });
        var circle = new zrender.Circle({
          shape: {
            cx: 200,
            cy: 200,
            r: 50
          },
          style: {
            fill: 'red',
            stroke: 'green',
            lineWidth: 2
          }
        });
        var point = new zrender.Polyline({
          shape: {
            points:[
              [300, 300],
              [301, 301]
            ]
          },
          style: {
            stroke: 'red',
            lineWidth: 1
          }
        });
        zr.add(rect);
        zr.add(line);
        zr.add(circle);

Echarts简介

官网介绍

1.官网地址：

https://echarts.apache.org/en/index.html

Echarts案例

https://echarts.apache.org/zh/tutorial.html

1.下载echarts.js到本地

2.然后在html文件中通过如下引入

<script src="echarts.min.js"></script>

或通过cdn免下载引入

<script src="https://cdn.jsdelivr.net/npm/echarts@5.3.2/dist/echarts.js"></script>

3.使用

初始化一个具有宽和高的容器

<div id="main" style="width: 600px ;height:600px;"></div>

在script中进行如下操作

初始化e’charts,绑定容器

<script>
        // init echarts
        var myid = document.getElementById("main");
        var myecharts = echarts.init(myid);
        // define option
        // invoking function
    </script>

设置option,这里包括我们想要绘制的图形类型，数据，x,y轴信息等

在官网示例中找

        // define option
        var option = {
            title:{
                text:"echarts 标题"
            },
            xAxis:{
                data:['food','digital','dress','bags']
            },
            yAxis:{
            },
            series:{
                type:"bar",
                data:[100,120,90,150]
            },
        }

将option传给myecharts实例就可以了

//Call the function and pass the arguments
        myecharts.setOption(option);

展示如图

Echarts案例

1.Echarts样式主题，显示加载动画，resize

参考：https://echarts.apache.org/zh/theme-builder.html

主题：

下载js主题

https://echarts.apache.org/zh/theme-builder.html

下载的文件名称为，purple-passion.js，将js放入到工程的js目录下

js/purple-passion.js

7.折线图设计-标记-线条-填充-间隙-缩放-堆叠

效果：

代码：

<!-- 容器 -->
    <div id="main" style="width: 600px;height: 600px;"></div>
    <!-- 写echarts代码 -->
    <script>
        var myCharts = echarts.init(document.getElementById("main"));
        myCharts.showLoading()
        var xDataArr = ['piter','tom','bill','li']
        var yDataArr = [88,92,60,70]
        var option = {
            animition:true,
            animationDuration:2000,
            animationEasing:"bounceOut", // linear  bounceOut
            animationThreshold:4,
            xAxis :{
                data:xDataArr,
                type:"category",
                boundaryGap:false
            },
            yAxis :{
                type:'value',
                scale:true
            },
            series:[{

                        ],
                },
                markLine:{
                    data:[
                        {type:"average",name:"average"}
                        ]
                },
                markArea:{
                    data:[
                        [{xAxis:'piter'},{xAxis:'tom'}],
                        [{xAxis:'bill'},{xAxis:'li'}]
                    ]
                },
                smooth:true,
                lineStyle:{
                    color:'green',

                label:{
                    show:true,
                    rotate:75,
                    position:"inside",
                },
                barWidth:'20%',
            },{
                type:"line",
                data:yDataArr,
                stack:'all',
                smooth:true,
                areaStyle:{}
            }
            ]
        }
        myCharts.hideLoading()
        myCharts.setOption(option);

中国地图

https://blog.csdn.net/ju__ju/article/details/104000887

datav json数据

http://datav.aliyun.com/tools/atlas/

地图基本使用：

1.加载该区域的矢量地图数据:

2.通过异步获取数据，并echarts.registerMap(‘china’,ret)注册到全局对象中

3.指明geo配置下的type和map属性，roam属性

4.通过zoom放大区域

5.通过center定位中心点

6.geo结合series

地图结合散点图

1.给series下增加新的对象

2.准备好散点数据，设置给新对象的data

3.配置新对象的type

type:effectScatter

4.散点图使用地图坐标系统

coordinateSystem:‘geo’

5.让涟漪的效果更加明显

rippleEffect:{

scale:10}

效果如下：

代码：

<div
