嗨，我有 2 个 google 图表(1 个日历和另一个 LineChart)，我收到 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，但今天我收到此错误，我只能显示字符或日历之一。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);
}
