General information for the website: Want to create a query for the google analytics embed api in javascript
Description of requirements/features: Want to create a query for the google analytics embed api in javascript which queries multiple dates and then stores the results as variables. As an example I have the below:

function drawKpis(ids) {
query({
'ids': ids,
'metrics': 'ga:sessions,ga:transactionRevenue',
'start-date': '2014-10-29',
'end-date': '2014-10-29'
})

list of dates

dates = [2014-10-29,2014-9-29,2014-5-29,2014-3-29]

then store the result of each query as a variable eg.

var 2014-10-29 = x
var 2014-10-29 = y
var 2014-10-29 = j
