Labels on a real time flot chart?

Question

I want to add labels on a real time flot chart which takes more than one variables. Here is a sample of the code:

//...switch code..

case "3":
   dataset = {
                "data1":    {label : "data1", data : dataArray[0]},
                "data2":    {label : "data2", data : dataArray[1]},
                "data3":    {label : "data3", data : dataArray[2]}                                  
            };

    data = [dataset];
    return  data;
    break;

The code works perfectly if i will not use labels. Example below:

//...switch code..
case "2":
    data = [
            dataArray[0],
            dataArray[1],
           ];
    return  data;
    break;

What am i doing wrong?

Any kind of example or solution will be perfect!

Assuming that the data here is then being used in a $.plot call, it's an incorrect format . You'll end up with an array of a single item, an object with key/value pairs.

What you need is an array of multiple objects:

[
  {label : "data1", data : dataArray[0]},
  {label : "data1", data : dataArray[1]},
  {label : "data1", data : dataArray[2]}
]

Also, ensure that dataArray[0] , etc.. are in the form of an array of arrays:

[
  [x1,y1],
  [x2,y2]
]
