title: Remove xticks in a matplotlib plot?
body: <p>I have a semilogx plot and I would like to remove the xticks. I tried:</p>
  
  <pre><code>plt.gca().set_xticks([])
  plt.xticks([])
  ax.set_xticks([])
  </code></pre>
  
  <p>The grid disappears (ok), but small ticks (at the place of the main ticks) remain. How to remove them?</p>
