When you wrote "import matplotlib.ticker", you meant "from matplotlib.dates import ticker" ?

I think I have a bug or something because I get an error like "ValueError: setting an array element with a sequence." with a lot of debug stuff from python and MatPlotLib
The line concerned is the one where I do plot(datetime_list,data_list).
It's very strange because just before I use "my_datetime.strftime("%d %H %M %S")" with my_datetime as an element of my list and it works perfectly.

Anyway, thanks a lot for the help.

you can get the date and time into a datetime object as follows:

import datetime
dt = datetime.datetime(2008,4,22,3,45,21)
print dt.strftime('%Y-%m-%d %H:%M:%S')
