Turn off axes in subplots

Question

I have the following code   import matplotlib pyplot as plt import matplotlib image as mpimg import matplotlib cm as cm  img   mpimg imread  lena jpg    f  axarr   plt subplots 2  2  axarr 0 0  imshow img  cmap   cm Greys r  axarr 0 0  set title  Rank   512    rank   128 new img   prune matrix rank  img  axarr 0 1  imshow new img  cmap   cm Greys r  axarr 0 1  set title  Rank    s   rank   rank   32 new img   prune matrix rank  img  axarr 1 0  imshow new img  cmap   cm Greys r  axarr 1 0  set title  Rank    s   rank   rank   16 new img   prune matrix rank  img  axarr 1 1  imshow new img  cmap   cm Greys r  axarr 1 1  set title  Rank    s   rank   plt show     However  the result is pretty ugly because of the values on the axes     How can I turn off axes values for all subplots simultaneously

import matplotlib pyplot as plt  fig  ax   plt subplots 2  2     To turn off axes for all subplots  do either    axi set axis off   for axi in ax ravel      or  map lambda axi  axi set axis off    ax ravel

You can turn the axes off by following the advice in Veedrac s comment  linking to here  with one small modification   Rather than using plt axis  off   you should use ax axis  off   where ax is a matplotlib axes object  To do this for your code you simple need to add axarr 0 0  axis  off   and so on for each of your subplots    The code below shows the result  I ve removed the prune matrix part because I don t have access to that function  in the future please submit fully working code    import matplotlib pyplot as plt import matplotlib image as mpimg import matplotlib cm as cm  img   mpimg imread  stewie jpg    f  axarr   plt subplots 2  2  axarr 0 0  imshow img  cmap   cm Greys r  axarr 0 0  set title  Rank   512   axarr 0 0  axis  off    axarr 0 1  imshow img  cmap   cm Greys r  axarr 0 1  set title  Rank    s    128  axarr 0 1  axis  off    axarr 1 0  imshow img  cmap   cm Greys r  axarr 1 0  set title  Rank    s    32  axarr 1 0  axis  off    axarr 1 1  imshow img  cmap   cm Greys r  axarr 1 1  set title  Rank    s    16  axarr 1 1  axis  off    plt show       Note  To turn off only the x or y axis you can use set visible   e g    axarr 0 0  xaxis set visible False    Hide only x axis
