All of the transforms go from some particular coordinate system to what one might call "screen coordinates": position in dots (pixels), with (0,0) in the lower left corner. transFigure and transAxes go from normalized coordinates to these screen coordinates; for transFigure, (0,0) and (1,1) are the lower left and upper right corners of the figure, and for transAxes they are the corners of the axes. I think that what you want to do requires something like the mechanism in QuiverKey: a derived artist with a draw method that figures out at draw time where to put the text; I don't think there is any other way to handle zooming while keeping the screen separation from a data point fixed. This may be a common enough task to warrant adding an "offset" tuple kwarg to the Text class, and maybe a transOffset as well.
