Google charts' addRows() function does not want to accept an array
提问by Joseph
I am trying to make a line chart, but Google Charts keeps throwing this error when I try to add a row of data:
我正在尝试制作折线图，但是当我尝试添加一行数据时，Google Charts 不断抛出此错误：
Error: Every row given must be either null or an array. @ ...corechart.I.js:162
错误：给定的每一行都必须为空或数组。@ ...corechart.I.js:162
Here are some example columns I tried. Making the columns works fine, and displays an empty graph as long as I don't add any rows.
这是我尝试过的一些示例列。使列工作正常，只要我不添加任何行，就会显示一个空图。
var data = new google.visualization.DataTable();
data.addColumn('number', 'timestamp');
data.addColumn('number', 'JPY');
data.addColumn('number', 'EUR');
data.addColumn('number', 'SEK');
data.addColumn('number', 'HKD');
data.addColumn('number', 'CHF');
//So far so good
Now, no matter how I try to pass an array with addRows(), I get the error. I have found similar questions here, but they've all failed for reasons of malformed code or used a different methodology to pass the code in. So here is a simplified test case, which still fails.
现在，无论我如何尝试使用 addRows() 传递数组，我都会收到错误消息。我在这里发现了类似的问题，但它们都因代码格式错误或使用不同的方法来传递代码而失败。所以这里是一个简化的测试用例，它仍然失败。
data.addRows([1,2,3,4,5,6]); //Breaks the chart
I also tried:
我也试过：
var myrow = new Array(1,2,3,4,5,6);
data.addRows(myrow);
I don't see how I can make this any more literally an array. I also passed two at once, because all the example code seems to pass multiple rows.
我不知道如何将它从字面上变成一个数组。我也一次传递了两个，因为所有示例代码似乎都传递了多行。
data.addRows([1,2,3,4,5,6],
[7,8,9,10,11,12]);
Still fails.
还是失败了。

Easy one. The addRows() method expects you to provide an array of arrays, not a single array for one row, and not separate parameters for each row. See the examplein the docs. Fixing your example, it should look like this:
简单的一个。addRows() 方法要求您提供一个数组数组，而不是为一行提供单个数组，也不要为每一行提供单独的参数。请参阅文档中的示例。修复您的示例，它应该如下所示：
data.addRows([[1,2,3,4,5,6], [7,8,9,10,11,12]]);
You might also prefer to use the addRow() method, which takes just one row at a time.
您可能还喜欢使用 addRow() 方法，该方法一次只处理一行。

I had same trouble while I was adding rows using for loop, but then you could find in documentationitself, addRows() expect array of Arrays, the thing you're trying to do can be achieved with simple addRow() without an 'S'.
addRow([1,2,3,4,5,6])
我在使用 for 循环添加行时遇到了同样的问题，但是随后您可以在文档本身中找到addRows() 期望数组数组，您尝试做的事情可以通过简单的 addRow() 实现，而没有 'S '。
addRow([1,2,3,4,5,6])
