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：
操作额外的提示框tooltip数据
addExtraTooltip: (extraTooltipData: Array<ExtraTooltipDataItemType>, id?: string) => void 新增额外的tooltip数据，如果id存在，则添加单个图表，否则添加所有图表
updateExtraTooltip: (extraTooltipData: Array<ExtraTooltipDataItemType>, id?: string) => void 更新额外的tooltip数据，如果id存在，则更新单个图表，否则更新所有图表
clearExtraTooltip: (id?: string) => void 清除额外的tooltip数据，如果id存在，则清除单个图表，否则清除所有图表

1. 操作额外的提示框tooltip数据

包括新增、更新、清除。
