Question

in django I am creating data series using datetime.date() objects, like this:

data.append([ddate, daily_score]) (ddate is a datetime.date() object, daily_score is integer)

How can I format them in the jquery flot diagram in the following way?

“Day/Month”?

I am doing this:

xaxis:{
       mode: 'time',
       timeformat: '%d/%m',
       minTickSize: [1, "day"]
},

but I get no graph to display.

If you read the flot documentation, you will see that the time format is supposed to be a Javascript timestamp, that is, milliseconds since epoch (January 1 1970 00:00:00 UTC). You pass a datetime object, so I guess that’s your problem.

You can easily convert your dates to milliseconds since epoch though:

import datetime
import time

msdate = time.mktime(datetime.date(2012, 5, 25).timetuple()) * 1000

After I wrote this suggestion I saw that the flot documentation also had a suggestion of how to do in python:

import datetime
import calendar

calendar.timegm(datetime.date(2012, 5, 25).timetuple()) * 1000

Otherwise your syntax looks ok from what I can tell.
