  29  <P> It is perfectly possible to combine the previous bar types to have
  30   grouped accumulated bar plots. This is done by just adding the
  31   different accumulated plots to a group bar plot, for example the
  32   following code would do that.<DIV class="phpscript"><CODE><FONT color="#000000">
