Question

我正在尝试在同一页面中添加谷歌柱形图，然后添加谷歌表格图表。添加柱形图时，它可以正常工作，但只要我添加表格图表，我就会在谷歌列图表的代码中出现错误。错误是：您使用错误的数据类型而不是DataTable或DataView调用draw（）方法。

有趣的是，当我删除提供Google Table图表所需的javascript文件链接的行时，此错误消失了。该行是：

以下是我的代码，有人可以帮我解决如何在同一页面添加Google柱形图和Google桌面图表的解决方案吗？

    mqtt = new MqttAndroidClient(
            MainActivity.this,
            "tcp://<org-id>.messaging.internetofthings.ibmcloud.com:1883",
            "d:<org-id>:MQTTdevices:watson-android"
    );

    MqttConnectOptions options = new MqttConnectOptions();

    options.setCleanSession(true);

    options.setUserName("use-token-auth");
    options.setPassword("<token>".toCharArray());

    Log.i(TAG, "attempting connection");

    try {
        mqtt.connect(options, new IMqttActionListener() {
            @Override
            public void onSuccess(IMqttToken asyncActionToken) {
                Log.i(TAG, "connected to mqtt");
                isconneted = true;
            }

            @Override
            public void onFailure(IMqttToken asyncActionToken, Throwable e) {
                Log.e(TAG, "mqtt connect failed", e);
                isconneted = false;
            }
        });
    } catch (MqttException e) {
        Log.e(TAG, "mqtt connect failed", e);
    }

google加载次数太多。
google.load和google.setOnLoadCallback只应调用一次。

材料列图表和表格图表所需的包是bar和table。

在这里，我删除了两个autoload脚本，并在柱形图后绘制了表格图表。

另外，我建议将<script>标记添加到<head>或<body>。

<!DOCTYPE html>

  <meta charset="utf-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />

  <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
  <script type="text/javascript" src="https://www.google.com/jsapi"></script>

  <script type="text/javascript">
    google.load("visualization", "1.1", {packages:["bar", "table"]});
    google.setOnLoadCallback(drawChart1);

    function drawChart1() {
      var abc = $.ajax({url:'kpi24.php',async:false,dataType:"json",}).responseText;
      var data = new google.visualization.DataTable(abc);

      var options = {
        chart: {
          title: '',
          subtitle: '',
        },
        bars: 'vertical',
        vAxis: {format: 'percent'},
        legend: { position: 'right', maxLines: 3 },
        colors: ['#20488D', '#EA922B']
      };

      var chart = new google.charts.Bar(document.getElementById('columnchart_material'));
      chart.draw(data, options);

      // draw table chart
      drawTable();
    }
  </script>

  <script type="text/javascript">
    function drawTable() {
      var abcnew = $.ajax({url:'kpi26.php',async:false,dataType:"json",}).responseText;
      var datanew = new google.visualization.DataTable(abcnew);
      var table = new google.visualization.Table(document.getElementById('table_div'));
      table.draw(datanew, {showRowNumber: true, width: '100%', height: '100%'});
    }
  </script>
</head>
