At present I'm using gnuplot to plot data against a time line. However the precision of the time line is in milliseconds but gnuplot only seems to be able to handle seconds.
I've looked at a couple of alternatives, but really I just need something like gnuplot that can cope with fractions of a second.
The programming language used for the main script is Python and whilst I've looked at matplotlib, it seems to be a lot more 'heavy duty' than gnuplot. As I won't always be the one updating the graphing side of things, I want to keep it as easy as possible.
Any suggestions?
Update
I'm using this with gnuplot:
set xdata time
set timefmt "%Y-%m-%d-%H:%M:%S"
However there is no %f to get milliseconds. For example, this works:
2011-01-01-09:00:01
but I need:
2011-01-01-09:00:01.123456
You can set the ticks format with
set format x '%.6f'
or (maybe, I have not tried it, as I now prefer to use Matplotlib and do not have gnuplot installed on my machines):
set timefmt "%Y-%m-%d-%H:%M:%.6S"
(note the number of digits specified along with the %S format string).
