Graphics labels

Hi, is it poissible to create a label on graph? Not legend in right side, but label on graph...

Like a marker or something?

Yes, forever visible on every part of pie for example. Now I have to move on every section of the pie to understand what it is called and takes a percentage. This is not very convenient.

Something like this

There is no way to make tooltips permanently visible at this time - they are only activated via mouseover.
