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.
