During the tournament, FM keeps track of the performance value (benefits)
of each contender. These values are stored in a series of raw data files
named
in the plot directory. FM also creates a file named evaluation.dem that
can be employed by Gnuplot in order to produce a visual
representation
of the evolution of the competitors along a tournament. Needless to say
that other tools might alternatively be utilized to interpret these data
files.
Interestingly, when using Gnuplot you can easily generate postcript representations of the evolution of the competitors by editing evaluation.dem and uncommenting some command lines wherever it is indicated.
Section 
shows how you must proceed in order to obtain
the visual representation offered by Gnuplot.
We must remind you that all the relevant data yielded during a tournament session are also available from the FM database whenever this capability has been enabled.
