在Google Chart Documentation中，您必须在图表中添加一个列表器。在您的特定情况下，您需要处理select事件。示例代码在网站上提供。以下是文档中的代码。

<html>

<head>
  <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
  <script type="text/javascript">
    google.charts.load('current', {
      'packages': ['corechart']
    });
    google.charts.setOnLoadCallback(drawChart);

    function drawChart() {

      var data = google.visualization.arrayToDataTable([
        ['Task', 'Hours per Day'],
        ['Work', 11],
        ['Eat', 2],
        ['Commute', 2],
        ['Watch TV', 2],
        ['Sleep', 7]
      ]);

      var options = {
        title: 'My Daily Activities'
      };

      // The select handler. Call the chart's getSelection() method
      function selectHandler() {
        var selectedItem = chart.getSelection()[0];
        if (selectedItem) {
          var task = data.getValue(selectedItem.row, 0);
          alert('The user selected ' + task);
        }
      }

      var chart = new google.visualization.PieChart(document.getElementById('piechart'));
      // Listen for the 'select' event, and call my function selectHandler() when
      // the user selects something on the chart.
      google.visualization.events.addListener(chart, 'select', selectHandler);

      chart.draw(data, options);
    }
  </script>
</head>

<body>
  <div id="piechart" style="width: 900px; height: 500px;"></div>
</body>

</html>
