How to solve when my tooltip has too many content

[LunaGoodnight]

============== Problem solved =================
My tooltip will display extensive information in my donut chart. However, I noticed that it doesn't show all the content, and some parts are cut off due to the positioning of the chart on the page. Is there a solution to this issue?

Oh I find that I can change css and give it fixed on screen!
