need some advice on x y plot

[nephish at xit.net]

the time is DateTime.DateTime object from a mySQLdb query.
the value is a number anywhere between 0 and 15.
the datetime is formatted like 2005-10-20 08:40:34

i could strip it and make a timestamp out of it. but reading the
number of seconds since january of 1970 doesn't make a neat chart.

any suggestions?

oh, and can you output from Gnuplot to a png or jpeg or something like
that.
the Gnuplot documentation says that it can make a bitmap png but i dont
know how to do that with the python wrapper. the docs for this are a
little cryptic.
still a newbie here. if you know a good tutorial on this, i would
really appreciate the link.

thanks for your time, and brain
