title: make only left subplots and bottom subplots (in MxN panels) contain x and y axis labels
body: <p>Is there any way in a panel of NxM subplots to just have the axes being shown for the left column and bottom row.</p>
  
  <pre><code>A|N|N|N
  A|N|N|N
  A|N|N|N
  A|A|A|A
  </code></pre>
  
  <p>Where A = axis and N = no axis</p>
  
  <p>Sometimes my subplots are 10x8, 3x4, 4x9 etc. and they all have the same x and y axis. I just want it to appear on the very left and the very bottom of that subset. At the moment I have to know which axis it is plotting to and do</p>
  
  <pre><code>    if (figi-1) % 7 != 0:
          ax.set_yticklabels([])
  
      if figi &lt; 29:
          ax1.set_xticklabels([])
  </code></pre>
  
  <p>I want to generalise this for any NxM panel arrangement without having to know before hand.
  Thanks.</p>
  
  <p>EDIT: I have found a way to do the y-axis. I setup the number of panels wide using:</p>
  
  <pre><code>nwide = 12
  nhigh = 5
  </code></pre>
  
  <p>Which means I can just do </p>
  
  <pre><code>if (figi-1) % nwide != 0:
      ax.set_yticklabels([])
  </code></pre>
  
  <p>Any ideas for bottom?</p>
  
  <p>EDIT: Worked it out. x-axis is as follows:</p>
  
  <pre><code>if figi &lt; (nwide*nhigh) - nwide:
      ax.set_xticklabels([])
  </code></pre>
