// List off all "countTxt" objects to demonstrate how to 
// iterate over a json object that contains nested
// arrays containing data. In your example, you have two arrays
// that each contain json data.
for (var i in jsonObject) {
    for (var j in jsonObject[i]){
        console.log(jsonObject[i][j].countTxt);
    }
}

// the above loop will print out the following:
/*
Unique visitors 
Total time spent on page 
Buyer logins 
Searches 
Views of our member pages 
Total vists 
Unique visitors 
Total time spent on page 
*/

// If you want to target a specific item in the jsonObject, you do // so like this:

// Grab the second object in the data array:
var secondObjectInJsonData = jsonObject[1];
console.log(secondObjectInJsonData);
// secondObjectInJsonData -> [Object,...
