Editing the XML
I know I can format XLABEL, but I couldn't add anything to the YVALUE. I was hoping I could manipulate it to get the percentage. So for, nothing has worked.
<data>
<dataset style="{font-size:9px;color:#767a7f;}" size="9" width="2" color="#272b4b" label="Dataset%20Label" dotsize="5" opacity="80" abstraction="4" outline="#5a6484" linecolor="#5a6484" type="pie">
<?php do { ?><point >
<label><?php echo($row_WADWCexercise['XLABEL']); ?></label>
<value><?php echo($row_WADWCexercise['YVALUE']); ?></value>
</point><?php } while ($row_WADWCexercise = mysql_fetch_assoc($WADWCexercise)); ?>
</dataset>
</data>
