That is one method that i have used, but i don't think it is ideal. My data can
be a wide range of things, sometimes the coordinates of a bunch of many
particles, sometimes the track of one. If I save just an array of numbers it
can get a bit confusing. So it would be useful to be able to save everything
needed to make the plot.
