You can set the showDataTips property of the LineChart to true. The property is defined in the ChartBase base class, which LineChart extends. More information about showDataTips is here:

You can customize what is displayed in the data tip callout by specifying a custom dataTipFunction.
您可以通过指定自定义dataTipFunction来自定义数据提示标注中显示的内容。
Using data tips will give you call outs as you mouse over the points that make up the line. If you want to provide information about the line in general you should couple the chart with a Legend to describe what the line represents. Creating a legend is as simple as this (where lineChart is the id value of your LineChart):
当您将鼠标悬停在构成线的点上时,使用数据提示将为您提供标注。如果您想提供有关该行的信息,您应该将图表与图例耦合以描述该行代表的内容。创建图例就像这样简单(其中lineChart是LineChart的id值):
<mx:Legend dataProvider="{lineChart}" />
