d3.js - crossfilter and dc.js line chart to plot every data point in ascending/descending order -

-

my data consists of simple information contracts. simplified each 1 looks this:

{     "id": 1234567890,     "district": "districtname",     "city": "cityname",     "test": "testnumber",     "date": "2015-03-15",     "score": 0.0 - 1.0 }

i have simple dc.barchart number of tests per day , dc.rowchart districts , 1 cities filter displayed data crossfilter.

what need line chart plots every score of every contract in ascending or descending order. mean not want group data score plot every score on y-axis , have nothing on x-axis. assuming data plotted in ascending order resulting picture ever increasing graph. see below:

line chart

how do data lives inside crossfilter instance, dc.js , d3.js?
