title: Matplotlib: show labels for minor ticks also
body: <p>In <code>matplotlib</code>, when I use a <code>log</code> scale on one axis, it might happen that that axis will have <strong>no major ticks</strong>, <strong>only minor</strong> ones. So this means <strong>no labels</strong> are shown for the whole axis.</p>
  
  <p>How can I specify that I need labels also for minor ticks?</p>
  
  <p>I tried:</p>
  
  <pre><code>plt.setp(ax.get_xticklabels(minor=True), visible=True)
  </code></pre>
  
  <p>... but it didn't do the trick. </p>
