but x axis didn't start 23:33:58.it start 00:00:00 mean 12.00 , draw in 23:59:00.so not requirement .i want solve problem please guide me.

you can pass timestamp date can solve problem.then identify date , time.so can solve this.in example parse timestamp this.

var parsetime = d3.time.format("%y-%m-%d %h:%m:%s").parse;

then json format timestamp change this

"timestamp": "2011-01-01 23:33:58"

then think can solve it.
