Вывод нескольких SQL запросов на график. js

/ 19 апреля 2020

Итак, у меня есть диаграмма, созданная на диаграмме. js, которая должна выводить результаты моих sql запросов на диаграмму, однако при запуске кода каждый раздел диаграммы отображает «1» каждый раз. Таким образом, если разделы на диаграмме должны быть 12,2,5,9,11 из запросов, показанных в коде, он просто показывает 1,1,1,1,1. Есть идеи, где я ошибся? 

  <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);

      ?>
      ],
