ECharts案例学习笔记——2020.08.28
一、案例技术目录（数据可视化）
1、使用技术
①基于 flexible.js + rem 智能大屏适配
② VScode cssrem 插件
③ Flex 布局
④ Less 使用
⑤基于 ECharts 数据可视化展示
⑥ ECharts 柱状图数据设置
⑦ ECharts 地图引入
2、ECharts基础配置
① series
—系列列表，每个系列通过 type 决定自己的图表类型。
—图标数据，指定什么类型的图标，可以多个图标重叠。
② xAxis：直角坐标系 grid 中的 x 轴
— boundaryGap：坐标轴两边留白策略 true，这时候刻度只作为分割线，标签和数据点都会在两个刻度之间的带（band）中间。
② yAxis：直角坐标系 grid 中的 y 轴
③ grid：直角坐标系内绘图网格
④ title：标题组件
⑤ tooltip：提示框组件
⑥ legend：图例组件
⑦ color：调色盘颜色列表
——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
二、案例演示结果
三、案例代码
