You can use the annotate command to place text annotations at any x and y values you want   To place them exactly at the data points you could do this  import numpy from matplotlib import pyplot  x   numpy arange 10  y   numpy array  5 3 4 2 7 5 4 6 3 2    fig   pyplot figure   ax   fig add subplot 111  ax set ylim 0 10  pyplot plot x y  for i j in zip x y       ax annotate str j  xy  i j    pyplot show     If you want the annotations offset a little  you could change the annotate line to something like  ax annotate str j  xy  i j 0 5
