当前 dataset 元素有颜色，但是如何将当前 dataset 标签放入 tooltip，从 xAxis 交换标签?

There is a color of current dataset element, but how can I put current dataset label into tooltip, exchange for label from xAxis?

推荐答案

在您的选项中将 multiTooltipTemplate 设置为 "<%=datasetLabel%> : <%= value %>" 以执行此操作.

In your options set multiTooltipTemplate to "<%=datasetLabel%> : <%= value %>" to do this.
