<H3><A NAME="8_2_7">8.2.7 Using grouped accumulated bar graphs</A></H3>
<P> It is perfectly possible to combine the previous bar types to have
 grouped accumulated bar plots. This is done by just adding the
 different accumulated plots to a group bar plot, for example the
 following code would do that.<DIV class="phpscript"><CODE><FONT color="#000000">
