title: Remove Gridlines from Google column chart
body: <p>I am using the google column chart from this example:</p>
  
  <p><a href="https://developers.google.com/maps/documentation/javascript/examples/elevation-paths" rel="nofollow">https://developers.google.com/maps/documentation/javascript/examples/elevation-paths</a></p>
  
  <p>and I want to remove the horizontal gridlines, after searching for apparently below is supposed to make them invisible (I tried with <code>hAxis</code> too) but it does not seem to be effecting the chart at all...</p>
  
  <pre><code>vAxis: {
      gridlines: {
          color: 'transparent'
      }
  }
  </code></pre>
  
  <p>Why is this not doing anything?</p>
