title: Google Chart, how to move annotation on top of columns
body: <p>I'm using Google Chart's stacked column chart, what i wanna achieve is to display the total on top of each column and i'm using annotation for this. As you look at the image, somehow only the annotation on the 5th column (1,307.20) is working as expected. </p>

  <p>As i investigate , this seem like a bug of Google Chart , this bug can be explained like below</p>
  
  <pre><code>[[Date, Car, Motobike, {role: :annotation}],
  [June 2015, 500, 0, 500],
  [Feb 2015, 500, 600, 1100]]
  [March 2015, 700, 0, 700],
  </code></pre>
  
  <p>With the above data, the annotation for Feb 2015 is the only which is displayed correctly , the other 2 do not since the last value of then is 0 , when I change the last value to 1 for June and March , the annotation is displayed correctly.</p>
  
  <p>Then I think of a work around is to always display the "non-zero" data on top , and here's the result:</p>
  
  <p><img src="https://i.stack.imgur.com/gTqTi.png" alt="enter image description here"></p>
  
  <p>The annotations are moved on top properly , but as you can see, it's located within the column and what i want to achieve is to move it on top of the column .</p>
  
  <p>I'm stuck with this for a while , Google Documentation doesn't help much with this case. Any help would be highly appreciated</p>
