"dateFormatter" is not defined -- I think you mean "formatter"
When I run this example with this change, I get tick labels with the
hour, minute and second as indicated...
Note recent versions of maptlotlib can takes dates explicitly (it will
handle the conversion for you). I would write this example as
(fig.autofmt_xdate will handle the ticklabel rotation for you)
import datetime
import dateutil.parser
import matplotlib.dates as mpldates
import matplotlib.pyplot as plt
ids = [1,2,3,4,5,6]
str_dates = ['2006-07-29 11:01:01','2006-07-29 10:02:03','2006-07-31 00:00:00',
'2006-08-01 10:11:12','2006-08-02 09:09:09','2006-08-03 08:08:08']
dates = [dateutil.parser.parse(s) for s in str_dates]
formatter = mpldates.DateFormatter('%m-%d-%y %H:%M:%S')
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(dates, ids, 'o')
ax.xaxis.set_major_formatter(formatter)
fig.autofmt_xdate()
ax.set_title("test dates")
plt.show()
