yes no bar using php

Hi below is my yes or no BAR,

For bar i have three image..

image_left is left side curve image, image_center is the center square image image right is right side curve image,

This below is my php function , am just increasing the center square image width , no other extra stuff i did for bar graph

function recommend_chart_yes_no($chartData,$img_path_is=NULL){
   global $tableSize;
   $span_no_left;
   global $span_no_right;
   $img_path = $img_path_is."chart/style";
   $maxValue = 0;

   // First get the max value from the array
   foreach ($chartData as $item) {
      if ($item['value'] > $maxValue) $maxValue = $item['value'];
   }
   // Now set the theoretical maximum value depending on the maxValue
   $maxBar = 1;
   while ($maxBar < $maxValue) $maxBar = $maxBar * 10;

   // Calculate 1px value as the table is 300px
   $pxValue = ceil($maxBar/$tableSize);

   // Now display the table with bars
    echo "<table width='150' border='0' cellspacing='0' cellpadding='0'>";
   foreach ($chartData as $item) {
      $width = ceil($item['value']/$pxValue);

      if($item['title']=="Yes"){

        echo "<tr><td width='24'><span class='feed-survey-yes-txt'>".$item['title']."</td>";
        echo "<td width='100' height='25' class='feed-survey-percentage-bg'><div class='feed-survey-percent-container'> <span class='feed-survey-percent-green-left'></span> <span class='feed-survey-percent-green-center' style='width:".$width."px;'></span> <span class='feed-survey-percent-green-right'></span> </div></td>";
        echo "<td width='21' align='left' class='feed-survey-percentage-txt'>".$item['value'].'%</td></tr>';
      }else{

        echo "<tr><td width='24'><span class='feed-survey-no-txt'>".$item['title']."</td>";
        echo "<td width='100' height='25' class='feed-survey-percentage-bg'><div class='feed-survey-percent-container'> <span class='feed-survey-percent-red-left'></span> <span class='feed-survey-percent-red-center' style='width:".$width."px;'></span> <span class='feed-survey-percent-red-right'></span> </div></td>";
        echo "<td width='21' align='left' class='feed-survey-percentage-txt'>".$item['value'].'%</td></tr>';
      } 
   }
   echo '</table>';

}
recommend_chart_yes_no($chartData,$img_path_is=NULL)

$chartData is the array , passing the width size for YEs and No Bar

My problem is ,

if YES reached the 79% means the bar showed in the graph somthing like 98%, This is wrong...So How to show the grpah correctly,

Please guide..
