JSON

Hello. How to cast one type to another type ? Needed to build a graph.

Answer 1

Make an object, process it and again translate it into json:

var tempObject = JSON.parse(json)
var tempArray = [];
for (var i = 0; i < tempObject.values.length; i++) {
  tempArray.push([tempObject.values[i].x,tempObject.values[i].y])
}
var result = JSON.stringify(tempArray);
