我用google.visualization.arrayToDataTable(loadGraphData);调用散点图
其中loadGraphData是以ArrayList<ArrayList<String>>的形式从支持bean生成的，如下所示：
"[['Date','Variable'], [0, 9.66], [1, 9.24], [2, 8.73], [3, 8.50]...]"
数据不是使用var加载图形，但是如果我将输出粘贴到其位置（没有引号），则代码可以正常显示数据。有没有方便的方法来删除引号，或者我采取了错误的方法？
顺便说一句，我已经用0,1替换了日期......因为这导致了一个不同的错误，我还没有解决。数据来自JSF支持bean，摘录如下：
public ArrayList graphData(int variable, int nodeNumber)
{
Collection dataValues = dataValuesFacade.findVariable(currentNodes.getCurrentNodes().get(nodeNumber), variable);
ArrayList <DataValues> dataValuesArray = new ArrayList();
dataValuesArray.addAll(dataValues);
dataValues = dataValuesFacade.findVariable(currentNodes.getCurrentNodes().get(nodeNumber), 0);
ArrayList<DataValues> timeValuesArray = new ArrayList();
timeValuesArray.addAll(dataValues);
ArrayList <DataPairs> dataPairs = new ArrayList();
dataPairs.add(new DataPairs());
ArrayList<ArrayList<String>> returnData = new ArrayList<>();
ArrayList<String> newAL = new ArrayList();
newAL.add("Date");
newAL.add("Variable");
returnData.add(newAL);
//Gson gson = new Gson();
for (int i=0;i<dataValuesArray.size();i++)
{
String varTimestamp = dataValuesArray.get(i).getdTimeStamp().toString();
String dateTimestamp = timeValuesArray.get(i).getdTimeStamp().toString();
String tempVariable = dataValuesArray.get(i).getdVariable().toString();
String tempDate = timeValuesArray.get(i).getdVariable().toString();
if ((varTimestamp.equals(dateTimestamp))&
(dataPairs.get(i).getXdateStamp()==null)&
(dataPairs.get(i).getYvariable()==null)&
(dataPairs.get(i).getTimeStamp()==null))
{
dataPairs.get(i).setTimeStamp(dateTimestamp);
dataPairs.get(i).setYvariable(tempVariable);
dataPairs.get(i).setXdateStamp(tempDate);
ArrayList<String> tempAL = new ArrayList();
tempAL.add(i+"");
tempAL.add(tempVariable);
returnData.add(tempAL);
dataPairs.add(new DataPairs());
}
}
//String rt = gson.toJson(returnData);
return returnData;
}
它很乱，但我一直在尝试各种需要清理的解决方案。
谢谢
确切输出如下：

答案 0 :(得分：1)
它不起作用，因为arrayToDataTable()成员函数需要一个Array作为参数，而你传递一个String。
可以使用的一个选项是首先解析作为JSON传递给您的数据。唯一的问题是包裹Date和Variable的单引号。单引号不是有效的JSON。如果您能够更改响应，则可以执行以下操作：
google.visualization.arrayToDataTable(JSON.parse(loadGraphData));
否则，如果你需要处理单引号，可以用双引号替换它们，然后解析为JSON：
google.visualization.arrayToDataTable(JSON.parse(loadGraphData.replace(/'/g, '"'));
