The question is clear but the title is not as precise as it could be  My answer is for those who came looking to change the axis label  as opposed to the tick labels  which is what the accepted answer is about   The title has now been corrected    for ax in plt gcf   axes      plt sca ax      plt xlabel ax get xlabel    rotation 90

For bar graphs  you can include the angle which you finally want the ticks to have  Here I am using rot 0 to make them parallel to the x axis  series plot bar rot 0  plt show   plt close

Pass param rot 0 to rotate the xticks   import matplotlib matplotlib style use  ggplot   import matplotlib pyplot as plt import pandas as pd  df   pd DataFrame    celltype    foo   bar   qux   woz     s1   5 9 1 7    s2   12 90 13 87    df   df   celltype   s1   s2    df set index   celltype   inplace True  df plot kind  bar  alpha 0 75  rot 0  plt xlabel     plt show     yields plot
