 <div id="chart_div"></div>

  **<?php $time= $_GET["sec"];?><br>**

chart.js

  var data = google.visualization.arrayToDataTable([
    ['Time', 'Time taken by worker'],
    ['Worker 1 ', 200],
    ['Worker 2', 150],
    ['Worker 3', 300],
    ['Worker 4', 160],
    ['Worker 5', 140],
    ['Time taken by you is', time]
  ]);

Answer 1

Try Below

Define Time Var before load chart.js

<script>
    var TIME_VAR = '<?=$_GET["sec"];?>';
 </script>

Then load <script src="chart.js"></script>

In chart.js you can use TIME_VAR

var data = google.visualization.arrayToDataTable([
    ['Time', 'Time taken by worker'],
    ['Worker 1 ', 200],
    ['Worker 2', 150],
    ['Worker 3', 300],
    ['Worker 4', 160],
    ['Worker 5', 140],
    ['Time taken by you is',TIME_VAR]
  ]);
