前言
简介：本文将从头开始，带你快速上手 echarts最常用图例—饼图 准备：请自行先将echarts图例引入你的项目，本文不多介绍。（引入 echarts教程：http://t.csdn.cn/mkTa4） 心得：echarts 的基础使用还是较为简单的，看起来属性很多，但是自己上手多写几个图，慢慢的就会发现并没有那么的难，孰能生巧
一、初识饼图
因为引入echarts图例后，改变图例的东西都在option配置项中，所以我下面只贴出 option中的代码，html结构和echarts引入挂载等代码就不多赘述
二、小试牛刀
2.1 玫瑰图配置项详解
2.2 全量代码
option = {
color: ['#18F6F8', '#288CFC', '#FFD91A'], // 配置各版块颜色
legend: {
top: '10px', // legend位置距离顶部10px
icon: 'circle', // 将legend图标改为小圆点 // legend图标宽度
itemWidth: 10, // legend图标宽度
itemHeight: 10 // legend图标高度
},
tooltip: {
confine: true,
trigger: 'item',
formatter: '{b} : {c}' // 鼠标hover时展示啥数据
},
series: [
{
avoidLabelOverlap: false,
type: 'pie', // 图例类型：饼图
roseType: 'area', // 玫瑰图
center: ['50%', '50%'], // 图例在容器中的位置，第一个控制左右，第二个控制上下
radius: ['20%', '60%'], // 20%：内部空白圆的直径，60%：外部圆环的直径
label: {
formatter: '{b}\n-------------\n{d}%\t{c}', // 自定义lable处展示那些数据及其格式
fontSize: 16 // 字体大小
},
labelLine: {
length: 50, // 挨着图例的直线的长度
length2: 20 // 挨着文字的直线的长度
},
data: [ // 图例数据，与右图对应
{
name: '大一',
value: 2100
},
{
name: '大二',
value: 2502
},
{
name: '大三',
value: 3156
}
]
}
]
};
2.3 快速体验
在线编辑网址：https://www.isqqw.com/echarts-examples/zh/editor.html?c=pie-simple&lang=js
打开在线编辑网址，将2.2的全量代码复制粘贴进左侧，即可在右侧看到图例，自行修改其中的配置项，然后点击运行，即可看到不同配置项对于echarts图例的作用。
三、常用图例
