title: Place my own controls overlapping Google visualization chart
body: <p>I'd like to add paging controls to my Google Visualization bar chart, similar to the one described <a href="https://groups.google.com/forum/#!topic/google-visualization-api/dxNifFZNJbQ" rel="nofollow">here</a> (keywords: thenez101 Google Visualization BarChart Paging), but instead of flowing my paging controls around the Google bar chart, I'd like to place them on top of the chart. When I place my controls inside the chart's div, however, I see them only until the chart is drawn. </p>
  
  <p>Assigning my controls a CSS class whose z-index property I have changed to positive and negative has not worked. Perhaps I can change their z position after my ready event has fired? Has anyone succeeded in getting this working? </p>
  
  <p>Thanks, BH</p>
