title: Google Charts how do I hide the value = 0
body: <p>Is it possible to hide <code>null</code> values on <code>hAxis</code>?
  or better to set <code>pointSize: 0</code> when the point is on the <code>hAxis</code></p>
  
  <p>if yes, which Option?</p>
  
  <p>I tried a <code>ComboChart</code></p>
