plot_date() - Correct format to plot

Hi,

I would like to be able to plot dates along the X axis' with values up the
Y. However Im having problems with the correct format in order to pass to
plot_date().

This is what I have so far: (example)

···

####################################
List = [ [datetime.datetime(2008, 7, 12, 5, 12)], ['46.8'] ]

plot_date(List[0], List[1])
#####################################
Returns error:

c = numeric.array(data, dtype=tc, copy=True, order=order)
ValueError: setting an array element with a sequence.
#####################################

I have looked at the pylab example for plot_date, however it uses a drange()
to figure out the dates and doesn't show me how to do it one by one.

Thank you for your time.

Hi

Have a look at pylab.date2num()
