Preference: Info-tips (info tooltips) or stationary info-areas for Scatter Plots?

I’ve seen two different ways to display information about a point on an scatter plot

  1. A tooltip (info tip) which appears next to your cursor
  2. When you hover over a point, information will display in the same location regardless of what point was clicked (on the bottom or the side or the chart).

There are benefits to both. I was hoping to find some best practices for these two ways to display information.

What do people usually prefer?

a true tooltip has the benefit of always being close to you point which you are hovering over; your eyes do not need to travel far to get to the information. On the other hand. I can see where it would get annoying to continually see the tooltip blinking off and on as you move between 300-400 different data points.
