title: Positioning strings to x-axis with same spacing
body: <p>In Python, I have two lists that each contain some elements</p>
  
  <pre><code>Chemical_elements= [11,12,20,21.1,22,23,24,25,26]        
  Other_values=[0.1,0.2,-0.03,0.1,0.2,0.2,0.2,0.2,0.2]
  </code></pre>
  
  <p>Now I want to plot a simple figure as <code>x=Chemical_elements</code> and <code>y=other_values</code>.</p>
  
  <p>The problem I'm facing is to assign the x-axis tickets into strings namely:</p>
  
  <pre><code>xticks=['Na','Mg', 'Ca', 'Sc', 'Ti', 'v' ,'Cr','Mn','Fe']
  </code></pre>
  
  <p>I tried the following:</p>
  
  <pre><code>locs, labels = xticks()
  
  xticks(np.arange(10, 70, step=5))
  
  xticks(np.arange(10), ('Na','Mg', 'Ca', 'Sc', 'Ti', 'v' ,'Cr','Mn','Fe'))
  </code></pre>
