<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0">
          <tr>
            <td width="25%" height="100%" align="center" valign="bottom" scope="col" ><div align="center"><? echo "<font color='red' size='2' align='center'>$data_poll[0] %</font>"."<BR>"."<IMG SRC='picture/bar3.png' height='$width_bar0 ' width='60'>"?></div></td>
            <td width="25%" height="100%" align="center" valign="bottom" scope="col"><div align="center"><? echo "<font color='red' size='2' align='center'>$data_poll[1] %</font>"."<BR>"."<IMG SRC='picture/bar4.png' height='$width_bar1 ' width='60'>"?></div></td>
            <td width="25%" height="100%" align="center" valign="bottom" scope="col"><div align="center"><? echo "<font color='red' size='2' align='center'>$data_poll[2] %</font>"."<BR>"."<IMG SRC='picture/bar1.png' height='$width_bar2 ' width='60'>"?></div></td>

          </tr>
