title: Google Charts hAxis tooltip
body: <p>I'm using Google Charts.
  I'm trying to display 15 stores and the number of clicks on each one.</p>
  
  <p>Now that's is working perfectly.</p>
  
  <p>My issue here is in the hAxis. As you can see the stores' names are incomplete, which is fine, but when i hover on an incomplete name, the tooltip is showing me an empty yellow box as shown in the picture below.
  <a href="https://i.stack.imgur.com/4V4Xm.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4V4Xm.jpg" alt="enter image description here"></a></p>
  
  <p>If i select the context of this tooltip, then i can read the full name:
  <a href="https://i.stack.imgur.com/xpCwP.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xpCwP.jpg" alt="enter image description here"></a> </p>
  
  <p>My question is: </p>
  
  <p>Is it possible to change the text color in this tooltip in order to read it?</p>
  
  <p>Thanks.</p>
