在 for 循环内，我尝试将变量数组插入一个对象内，而该对象又位于一个数组内。我试图将数据推送到这里: 
扩展 View : 
数据最终位置: 
这是我的代码:
let that.dynamicDataCollection3 = [];

哪个正在记录这个(将数据推送到对象之外):
that.dynamicDataCollection对象/数组的预期输出应该是这样的:
[

]
预期结果为图像: 
关于如何解决这个问题有什么想法吗？
最佳答案
更改此:
我向您的数据集模板添加了一个空数组data
let datasets = [
{
label: allDeptNames[i],
backgroundColor: lineColours[i],
backgroundColor: lineBackColours[i],
borderColor: lineColours[i],
borderWidth: 2,
data: [] // <- Add this
}
]
将 datasets.push(data ); 更改为 datasets[0].data = data.map(i => i[0]);
let allDeptNames = ["Dept 1", "Dept 2", "Dept 3", "Dept 4", "Dept 17"];
let insPerDay = [
