示例说明

vue-echarts-linkage 联动组件的基础示例。

注意：基础示例包含了最基本的联动功能，包括：
批量替换，适用于模板更新场景，实现模板图例所见即所得。
核心方法：replaceAllEchartsData: (newAllSeriesdata: OneDataType[][]) => void
切换为all-replace模式；
清空所有echarts实例为空白Echarts；
处理echarts实例数量变化；
各个Echarts实例添加新的series。
获取模板信息：getTemplateTagsOption: () => Array<Array<DragItemType>>。

1. 批量替换数据

批量更新数据，保持图例不变，数据更新。
