Steps to reproduce

Wait for the timer to change the data to Null, then need to manually hover, the chart will be re-rendered,

1.Note that the chart animation needs to be turned off, otherwise, re-render, no expected effect 2.When the data is null, expect to behave as a breakpoint and chart re-render
