title: Google Charts transparent background not working
body: <p>I am trying to make the background transparent for some charts I have made with google charts.  They work perfectly in everything except IE7 and 8, I get a white backgound.</p>
  
  <p>I have tried every combination I can find for the color attribute to change it but nothing works.</p>
  
  <p>The only thing left to try was a suggesting that someone made on here a few months ago for someone else with the same issue.  Their suggestion was... </p>
  
  <p>For a transparent background, use chf=bg,s,FFFFFF00</p>
  
  <p>But I have no idea how to implement this?</p>
