我试图改变图表的价值如下

<!doctype html>
<head>
<script>
var chart1; // globally available

$(document).ready(function() {
    var chart = 'pie'
    $("select").change(function(){
        chart = $('#chart').val();
        alert(chart);
    });

   chart1 = new Highcharts.Chart({
       chart: {
          renderTo: 'container',
          type: chart 
        },
        yAxis: {
           title: {
              text: 'Temprature'
           }
        },
        series: [{
           name: 'mach_1',
            data: [<?php 
            foreach($chart as $`row) {
            echo  $row['temp'].",";
            }
           ?>]
          }]
      });
});
</script>
</head>

<body>
  <div id="form">

    <label>Select a chart : </label>
    <select id="chart">
      <option>pie</option>
      <option>column</option>
    </select>

  </div>

  <div id="container"></div>

</body>
</html>

我知道这将改变选择图表的价值,但它不会改变图表本身.有任何想法吗？
