在chart.js中输出多个SQL查询

Question

因此，我在chart.js中创建了一个图表，该图表应在图表中输出我的sql查询结果，但是在运行代码时，图表的每个部分每次都显示“ 1”。因此，如果代码中显示的查询图表中的部分应为12,2,5,9,11，则它仅显示1,1,1,1,1。知道我哪里出错了吗？

  <script>
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
  type: 'doughnut',
  data: {
    labels: ['Body Pump', 'Spin Class', 'Yoga', 'Body Tone', 'Legs, Bums & Tums'],
    datasets: [{
      label: 'Total Number of Bookings',
      data: [
      <?php

      $resultbodypump = mysqli_query($db, "SELECT COUNT(SessionType) FROM bookings WHERE username = '".$_SESSION['username']."' AND SessionType = 'bodyPump'");

      $resultspinclass = mysqli_query($db, "SELECT COUNT(SessionType) FROM bookings WHERE username = '".$_SESSION['username']."' AND SessionType = 'spinClass'");

      $resultyoga = mysqli_query($db, "SELECT COUNT(SessionType) FROM bookings WHERE username = '".$_SESSION['username']."' AND SessionType = 'yoga'");

      $resultbodytone = mysqli_query($db, "SELECT COUNT(SessionType) FROM bookings WHERE username = '".$_SESSION['username']."' AND SessionType = 'bodyTone'");

      $resultlegsbumstums = mysqli_query($db, "SELECT COUNT(SessionType) FROM bookings WHERE username = '".$_SESSION['username']."' AND SessionType = 'legsBumsTums'");

      echo mysqli_num_rows($resultbodypump) . ",";
      echo mysqli_num_rows($resultspinclass) . ",";
      echo mysqli_num_rows($resultyoga) . ",";
      echo mysqli_num_rows($resultbodytone) . ",";
      echo mysqli_num_rows($resultlegsbumstums);

      ?>
      ],
