How can we hide or show custom tooltips on certain data points in one visual?

Hi Team,

We have a bar and line chart visual where we nned to show a custom tooltip which is a text data in the visual. 

So,when there is a matching data I want the tooltip to be displayed. But when there is no matching data, i am seeing blank tooltip with header names. Is there a way I can totally hide the blank tooltip and only display the tooltip when there is matching data?

Thanks,

A
