title: Change the marker thickness in matplotlib scatter plot
body: <p>I have the following marker in my python matplotlib scatter plot:</p>
  
  <p><a href="https://i.stack.imgur.com/lOKRD.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lOKRD.png" alt="enter image description here"></a></p>
  
  <p>made by the code:</p>
  
  <pre><code>plt.scatter(x,y,c=z,cmap=cm.bwr,marker='X',s=800,linewidth=1,edgecolor='k')
  </code></pre>
  
  <p>I want the X to be the same size, but I want the red part to be 'thinner'. More like a real 'X' I guess.</p>
  
  <p>Is this possible?</p>
  
  <p>Thank you.</p>
