D3 for YYYY-MM-DD i.e. 2013-02-04

Question

I get

Uncaught TypeError: Cannot read property 'length' of undefined

from my console on this line

var parseDate = d3.time.format("%Y-%m-%d").parse;

data.forEach(function(d) { d.Day = parseDate(d.Day); });

this is how my date is formatted in my json object day: "2013-02-04"

I suspect the "day" case is not correct. I can execute:

var parseDate = d3.time.format("%Y-%m-%d").parse;
parseDate( "2013-02-03" )

No problem (correct date displayed). You probably need to change your code to:

data.forEach(function(d) { d.day = parseDate(d.day); });

(note the lowercase "d" in "day")
