If you define myVal as:

var myVal = [ [1146096000000,69.36], [1146182400000,70.39], [1146441600000,69.60]];

then it is already json, and doesn't need to be parsed using parseJSON. You can simply set

data = myVal;

If myVal is defined as 

var myval = new Array();
myval [0] = "1146096000000,69.36";
myval [1] = "1146182400000,70.39";
myval [2] = "1146441600000,69.60";

Then myval is a json object containing strings. You can either parse out each elemnt of the array (e.g. using split) or define it like this:

var myval = new Array();
myval [0] = [1146096000000,69.36];
myval [1] = [1146182400000,70.39];
myval [2] = [1146441600000,69.60];

in which case, it is also already a json object and won't need to be parsed.

The only time you need to parse JSON is if the original data is a string representation of a json object, e.g. when getting the data from an ajax call.
