示例说明

vue-echarts-linkage 联动组件的拓展示例。

注意：拓展示例包含的功能，包括：

1. 多条数据进行首尾相连，合并为一条数据，中间以图表标线显示区分
2. 核心属性：oneDataType下的属性seriesLink: { isLinkMode: true, linkData: [ { label, data }, ... ] }
3. isLink 首尾相连模式，true：首尾相连，false：非首尾相连
4. 核心方法：replaceAllEchartsData: (newAllSeriesdata: OneDataType[][]) => void

1. 批量更新数据

• 多条数据进行首尾相连，合并为一条数据，中间以图表标线显示区分。
