title: XLSX Writer Hide Axis Line Only
body: <p>Given the chart below, I am looking for a way in XLSX-Writer to hide the bottom axis line without losing the categorical labels ([6,7,8,9]).</p>
  
  <p>I have tried using major and minor grid lines, but no dice (though this did hide the tick marks, which was one of my goals):</p>
  
  <pre><code>chart.set_x_axis({'major_tick_mark': 'none',
                   'minor_gridlines':{'visible':False}})
  </code></pre>
  
  <p>Thanks in advance!</p>
