Here's a sample of updates made to (older version) of class_admin.php ->

function db_results_schema($this, $display=1) { ....

<add> $answer_array = array();

  foreach($this->question as $question) {
  .... 

  if ($display) {
  ....

  <add>      
  if (is_array($question->answer)) {
           $answer_counter = 0;
            if ($question->type == 'mc_check') $answercount_display = $question->qnum;
            else $answercount_display = "1";

            foreach ($question->answer as $answer) {
               if ($question->type == 'mc_check')
                  $ans = $ans . '(q' . $answercount_display . ') ' .
                   $question->answer[$answer_counter] . '
';
               else  $ans = $ans . $answercount_display . ' ' .
                   $question->answer[$answer_counter] . '
';
               $answer_counter++;
               $answercount_display++;
            }
        }

which would create a datapoint legend looking like:
