Question

I have two one dimensionaly arrays – each of the same length; temperature and seconds. To create a scatter graph, I need it in the form;

var data = [
            [temperature[100],seconds[100]],
            [temperature[99],seconds[99]],
            [temperature[98],seconds[98]],
             ...
           ];

I can’t seem to work out how to do it, and I seem to be asking the wrong questions in Google.

Answer 1

Loop backwards through the arrays and create new arrays from each pair of items:

var data = [];
for (var i = temperature.length - 1; i >= 0 ; i--) {
  data.push([ temperature[i], seconds[i] ]);
}
