Uncaught TypeError: string is not a function - on google Chart

Question

您好，我有 2 个 google 图表（一个日历和另一个折线图），我正在获取 Uncaught TypeError: string is not a function 和 Uncaught TypeError: undefined is not a function。昨天它工作正常，我可以看到这两个，但今天我得到这个错误，我只能显示一个字符或日历。在单独的文件中，我没有收到任何错误，我修改了 json，它显示了我想要检索的数据。

此代码正在运行并绘制了两个图表，问题是您忘记加载折线图依赖项。

// Load the Visualization API and the piechart package.
google.load('visualization', '1', {'packages':["corechart"]});

google.load("visualization", "1.1", {packages:["calendar"]});
google.load("visualization", "1.1", {packages:["linechart"]});

// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawCalendar);


function drawCalendar() {

var data = new google.visualization.DataTable();
        data.addColumn('date', 'Date');
      data.addColumn('number', 'X');
      data.addRows([
        [new Date(2008, 0, 1), 1],
        [new Date(2008, 1, 14), 2],
        [new Date(2008, 9, 14), 12],
        [new Date(2008, 10, 14), 22],
        [new Date(2009, 1, 1), 30]
      ]);
    // Create our data table out of JSON data loaded from server.
      var chart = new google.visualization.Calendar(document.getElementById('calendar'));



        // Instantiate and draw our chart, passing in some options.

        chart.draw(data, options);

var data2 = new google.visualization.DataTable();
        data2.addColumn('date', 'Date');
      data2.addColumn('number', 'X');

      data2.addRows([
        [new Date(2008, 0, 1), 1],
        [new Date(2008, 1, 14), 2],
        [new Date(2008, 9, 14), 12],
        [new Date(2008, 10, 14), 22],
        [new Date(2009, 1, 1), 30]
      ]);
    var options = {
        title: 'Estado de Bateria',
        width: 800,
        height: 400,
        vAxis: {
        minValue: 0, 
        maxValue: 100
        }

    };

                // Instantiate and draw our chart, passing in some options.
         var chartBat = new google.visualization.LineChart(document.getElementById('battery'));


                chartBat.draw(data2, options);
}
