Echarts实战案例代码(28)：象形图与dataZoom组件实现大事记进度图

数据API

let xdata = ['2019-06-12', '2019-09-15', '2020-01-10', '2020-03-05', '2020-04-12', '2020-05-18', '2020-06-12', '2020-07-07'],
    data = [120, 90, 10, 80, 90, 20, 56, 150],
    infoData = ['漏刻有时发布', '数据分析系统', '磐安旅游签到', '物联网停车场', '刷脸支付大屏', '扎根版开发', '百度地图开发', '智慧城市3D开发'];
