Google Chart - uncaught error: not an array
提问by Latheesan
I have a php script that generates the google chart data and returns it in json encoded format. It's loaded into google chart using jQuery $.get() method. When I pass the return data to the google "arrayToDataTable" function like this:
我有一个 php 脚本，它生成谷歌图表数据并以 json 编码格式返回它。它使用 jQuery $.get() 方法加载到谷歌图表中。当我将返回数据传递给谷歌“ arrayToDataTable”函数时，如下所示：
var googleChartData = google.visualization.arrayToDataTable(chartData);
I get this error:
我收到此错误：
So, what I did was I dumped the value of my variable "chartData" and I got the following:
所以，我所做的是我转储了我的变量“ chartData”的值，我得到了以下信息：
So, what I did was, copy this data from console window into the "arrayToDataTable" function manually like this:
所以，我所做的是，将控制台窗口中的这些数据手动复制到“ arrayToDataTable”函数中，如下所示：
var googleChartData = google.visualization.arrayToDataTable([["Date Range","0001\/102\/0 Available","0001\/102\/0 Unavailable","0001\/102\/1 Available","0001\/102\/1 Unavailable"],["02\/10\/2013",0,1,110,11],["03\/10\/2013",0,1,189,11],["04\/10\/2013",0,1,189,11],["06\/10\/2013",0,1,189,10],["07\/10\/2013",0,1,187,10],["08\/10\/2013",186,11,0,1],["09\/10\/2013",186,11,0,1],["10\/10\/2013",0,1,186,11],["11\/10\/2013",0,1,204,11],["13\/10\/2013",0,1,204,11]]);
Now the chart renders (as expected, because the returned data from my php script is correct):
现在图表呈现（正如预期的那样，因为从我的 php 脚本返回的数据是正确的）：
This is a bit bizarre; does any one know why the chart doesn't work when it's loaded from the variable?
这有点奇怪；有谁知道为什么图表在从变量加载时不起作用？

I've solved it by changing arrayToDataTableline like this:
我已经通过像这样更改arrayToDataTable行来解决它：
var googleChartData = google.visualization.arrayToDataTable($.parseJSON(chartData));
