Before you iterate over your data you should somehow remove/skip the first line. In my opinion it is better to remove, cause if you would like to use later this array, then you have to skip again. I have two ideas:

before the iteration call:data = data.shift(); based on this: http://www.w3schools.com/jsref/jsref_shift.asp This will remove the first element.

Or if you are using lodash, than you can easily call data = _.tail(data); based on this: https://lodash.com/docs/4.16.4#tail
