The data set looks something like this, The data is from openstack ceilometer python API

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']
cols.append(col)
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.
