title: Show value of Google column chart
body: <p>I have a column chart using Google Visualization. </p>
  
  <p><a href="https://i.stack.imgur.com/AHb0B.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AHb0B.png" alt="enter image description here"></a></p>
  
  <p>Right now, in order for me to see each value, I have to hover on each graph to see the value. Example, <code>2.82 kbps</code></p>
  
  <p>I want to show all my value somewhere either on the top of each graph or inside the graph. </p>
  
  <p>How can I show something like that ? </p>
  
  <p>Any hints on that will be much appreciated ! </p>
