title: How to change rotation of xticks in matplotlib?
body: <p>I want to change the rotation of the xticks, but I am ending with x AND yticks rotated. How can I rotate just the xticks? </p>
  
  <p>Here is my code: </p>
  
  <pre><code># Plot mit Sidestepped 0/1
  
  sns.set(style="darkgrid")
  
  fig, ax = plt.subplots(1,2, figsize=(14,5))
  
  for i in range(len(ax)):
      ax[i].tick_params(labelsize=15)
      ax[i].set_xlabel('label', fontsize=17, position=(.5,20))
      ax[i].set_ylabel('label', fontsize=17)
  
  sns.countplot(x="page_name", hue="successful", data=mainDf, ax=ax[0]); 
  sns.countplot(x="industry", hue="successful", data=mainDf, ax=ax[1]);
  
  fig.suptitle('Categorical Features Count', position=(.5,1.1), fontsize=20)
  ax[0].set_title('Type by Industry', fontsize=18)
  ax[0].set_xlabel('Industry')
  ax[0].tick_params(rotation=50)
  ax[1].set_title('Success by Industry',  fontsize=18)
  ax[1].set_xlabel('Industry')
  fig.tight_layout()
  
  fig.show()
  </code></pre>
  
  <p>And here is what I get (x BUT unfortunately also yticks rotated! Look at just the left plot at ax[0]! I want to rotate just the xticks of the left plot!):</p>
