谷歌图表 - 未捕获的错误：不是数组 [英] Google Chart - uncaught error: not an array

问题描述

我有一个生成google图表数据并以json编码格式返回的php脚本。它使用jQuery $ .get（）方法加载到Google图表中。当我将返回数据传递给谷歌 arrayToDataTable 这样的功能：

  var googleChartData = google.visualization.arrayToDataTable（chartData）; 
  

我得到这个错误：

< img src =https://i.stack.imgur.com/11qLo.pngalt =

因此，我所做的是我倾倒了我的变量 chartData 的值，并得到以下结果：

因此，我所做的是将这些数据从控制台窗口复制到

  var googleChartData = google.visualization.arrayToDataTable（[[Date> arrayToDataTable  0001 \ / 102 \ / 0可用，0001 \ / 102\ / 0不可用，0001 \ / 102\ / 1可用，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]]）; 
  

现在图表呈现（如预期的那样，因为我的php脚本返回的数据是正确的）：

这有点奇怪;是否有人知道为什么图表在从变量加载时不起作用？解析方案

解决方案

arrayToDataTable 这样的行：

  var googleChartData = google.visualization.arrayToDataTable（$。parseJSON（chartData ））;

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:

var googleChartData = google.visualization.arrayToDataTable(chartData);

I get this error:

So, what I did was I dumped the value of my variable "chartData" and I got the following:

So, what I did was, copy this data from console window into the "arrayToDataTable" function manually like this:

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):

This is a bit bizarre; does any one know why the chart doesn't work when it's loaded from the variable?

解决方案

I've solved it by changing arrayToDataTable line like this:

var googleChartData = google.visualization.arrayToDataTable($.parseJSON(chartData));
