Answer 1

You can use follow method:

var freq = { a: 50, r: 25, m: 25 };
/*
dps = [  
   { label: "a",
     y: 50  },
   { label: "r",
     y: 25  },
   { label: "m",
     y: 25  }
];
*/
var dps = [];
var keys = Object.keys(freq);
keys.map((current,index)=>{
  dps.push({label:keys[index], y:freq[keys[index]]});
});
console.log(dps);
