Passing array values to each loop

Question

I am using a plugin that creates donut charts called easyPieChart. I need to update the data that is passed to the plugin. This is done by the following:

 $(this).data('easyPieChart').update(40);

This basically sets the value of the donut to 40%. I need to loop through a series of divs and update the donut charts in each one. If I was to do the following, all donuts would be updated to 40%:

$('.percentage').each(function() {
      $(this).data('easyPieChart').update(40);
});

I need to create an array of integers to pass, so as we are iterating on .percentage a different value is passed to each. So for instance, the first .percentage receives a value of 40, the second 60, etc.

if I had an array with all of the numbers, how would I use it with the each loop:

var numbToUse = [40,30,60];

The first argument of each is the index, so you can use it to get it's value, like the following:

var numbToUse = [40,30,60];

$('.percentage').each(function(i) {
      $(this).data('easyPieChart').update(numToUse[i]);
});
