BarChar add event for show y number?

[geekyzk]

This is my code
<BarChart margins={{top: 10, bottom: 50, left: 120, right: 10}} stackOffset={"wigget"} fill={'#3182bd'} data={customData(th2CDetailList)} width={1400} height={600} title={th2CDetailList[0][0]} yAxisLabel="数值" xAxisLabel="日期"/>

I would like to add a mouse event to show the value, but do not know how to add, you can ask what？
