Javascript delete JSON elements

Question

I have this JSON string in a PHP page:

{
  "elements": [{
    "type": "pie",
    "alpha": 0.3,
    "animate": [{
      "type": "fade"
    }, {
      "type": "bounce",
      "distance": 5
    }],
    "start-angle": 0,
    "tip": "#val# de #total# #percent#",
    "colours": ["#d01f3c", "#356aa0", "#C79810"],
    "values": [{
      "value": 1,
      "label": "procesador amd sempron 140"
    }, {
      "value": 1,
      "label": "procesador sempron le130"
    }, {
      "value": 1,
      "label": "procesador amd a4-3300 x2"
    }, {
      "value": 1,
      "label": "procesador intel celeron g530"
    }]
  }],
  "title": {
    "text": "Procesadores, Reinicio",
    "style": "color: #356aa0; font-size: 20px"
  },
  "bg_colour": "#FFFFFF",
  "x_axis": null
}

I call it like this:

$.getJSON("restart_proce.php", function(json)
{    
console.log(json);

I need to transform it to this:

[{\"value\": 1, \"label\": \"procesador amd sempron 140\" }, { \"value\": 1, \"label\": \"procesador sempron le130\" }, { \"value\": 1, \"label\": \"procesador amd a4-3300 x2\" }, { \"value\": 1, \"label\": \"procesador intel celeron g530\" } ]

I'm trying to delete elements like this:

delete json.elements[3];

but it doesn't delete anything. How can I make it work?

Removing an item from an Array:

There are several ways. The splice method is the most versatile:

data.items.splice(3, 1); // Removes three items starting with the 2nd,

splice modifies the original array, and returns an array of the items you removed.
