I need to ensure that the length of the key, values arrays are the same so I can plot them on a stackedAreaChart using nvd3 since there are two conditions that I need to follow... 我需要确保的长度key, values数组是一样的，所以我可以绘制他们在stackedAreaChart使用nvd3因为有两个条件，我需要遵循...
- Series should have the same time scale (range). 系列应具有相同的时间刻度（范围）。
- Series length, ie 'values' array length should be the same across all objects in data. 系列长度（即“值”数组的长度）在数据中所有对象之间应相同。
I tried following this fidde: http://jsfiddle.net/krispo1/nR6qN/2/ 我尝试遵循此方法： http : //jsfiddle.net/krispo1/nR6qN/2/
by doing this in the controller: 通过在控制器中执行以下操作：
get_scn_cst_data().then(function(costByScn){
var data2 = []
for(i = 0; i < costByScn.length; i++) {
console.log("i:", JSON.stringify(costByScn[i].values))
var data = costByScn[i].values;
if(data && Array.isArray(data)) {
console.log("is array")
}
data = data.map(function(series){
series.values = series.values.map(function(d,i){
return [data[2].values[i][0], d[1]]
})
return series;
});
}
console.log("data2: ", JSON.stringify(costByScn));
$scope.data_costByScn = costByScn;
})
but got this error: TypeError: data.map is not a function 但收到此错误： TypeError: data.map is not a function
----EDIT----- - - 编辑 - - -
made changes to fix the array but now getting this error at Cannot read property 'values' of undefined at this part: 进行了更改以修复数组，但是现在在Cannot read property 'values' of undefined此部分Cannot read property 'values' of undefined得到此错误：
data = data.map(function(series){
series.values = series.values.map(function(d,i){
return [data[2].values[i][0], d[1]]
})
return series;
});
why does values come back undefined? 为什么值返回未定义？ when I console log data, it looks to be an array with values 当我管理日志数据时，它看起来像是一个带有values的数组

simply the type error means you are trying to invoking .map on something which is not an array! 只是类型错误意味着您试图在不是数组的东西上调用.map！
before sending that data to the .map verify it to be a valid array 在将该数据发送到.map之前，请先将其验证为有效数组
you can use : if(data && Array.isArray(data)) { // your login goes here... } 您可以使用： if(data && Array.isArray(data)) { // your login goes here... }
