                                                  4counter_type': gauge'

My code looks something like this

    auth=v2.Password(auth_url="http://", username="user", password="pass", tenant_id='id')
    # Pubnub instance initilize
    sess = session.Session(auth=auth,verify=False)     #
    token = auth.get_token(sess)
    cclient = client.get_client(2, ceilometer_url="http:", token=token,verify=False)
    data = cclient.samples.list(meter_name ='cpu_util')
    thing = {}
    msg = {}
    cols = []
    def __unicode__(self):
      return unicode(self.data)
    for row in data:
        col = {}
        col['x'] = row['timestamp']
        col['y'] = row['counter_volume']
    msg['columns'] = cols
    thing['message'] = msg
    print thing
    print json.dumps(thing)

My intended out out something like this

    message: {
          columns: [
            ["x": 123, "y": "456"],
            ["y": 0.045, "x": "2015-06-30T15:53:55"]
**here x is counter_volume and Y is timestamp**
I need the output in this way because I want to plug this data into EON pubnub Charting Library. Problem is that no matter what I do it keeps on throwing me errors.I guess I need to learn some more how to manipulate list of dictionaries.
