    label: 'Sistem Informasi',
    data: [90, 120, 225, 185, 200],
    backgroundColor: 'rgba(72, 189, 122, 0.2)',
    borderColor: 'rgba(72, 189, 122, 1)',
    borderWidth: 1
}]

Answer 1

Your desired dataset look like an array of the objects, where every data within the curly braces is object. So if you want to put multidimensional array in JS, create each object in a variable, add data to that and then push that to the array. Like

let arr = [];
let obj1 = {}; //add data to this object
arr.push(obj1);
let obj2 = {}; //add data to this object
arr.push(obj2);
.
.
.
let objn = {}; //add data to this object
arr.push(objn)
