Re: [sr #3077] Produce graphs with more points than the standard graphs. -- September 10, 2013 - 15:17

That's ok, 10000 points doesn't take too much space.  I just generated
such a graph in Grace (using the equation x^2) and saved the file and
it was only 30K.  Part of the relax philosophy is to aim for the
highest quality possible.  The user can subsequently decrease that
quality if they desire.  That is why Gary Thompson created the float
module (now in lib) and you can see this as the <ieee_754_byte_array>
elements in the relax state and results file - this is the best
possible way of storing a floating point number and avoiding any
truncation what-so-ever!  You will find that relax is the most precise
of any dynamics software out there.

Regards,

Edward
