Following plots are supported:

$CMD --conv-fitness [ --scale SCALE ] [ PREFIX ] ...

	Plot population convergence graph using convergence data in files
	"conv*.txt" in the current directory. One line is drawn for each 
	node. It shows the fitness of the best timetable versus generation 
	count. Use the PREFIX option, if you used the "-o" option with 
	Tablix. Use the SCALE option to adjust the vertical scale. You can 
	use more than one PREFIX option to plot multiple convergence graphs 
	in one window. 

$CMD --fit-fitness [ --scale SCALE ] [ PREFIX ] ...

	Same as "--conv-fitness", except that an exponential function is also 
	drawn on the graph using least squares fitting. This can be used to
	get a rough estimate of the time required to find a solution. The
	SCALE parameter is used to adjust the horizontal scale in this case.

$CMD --functions [ --scale SCALE ] CONVFILE

	Plot the return value of each fitness function versus generation 
	count. Return values of mandatory fitness functions are plotted
	with thicker lines. CONVFILE must be a file with Tablix population 
	convergence data (usually named "conv*.txt"). Use the SCALE option 
	to adjust the vertical scale.

Prepend "EPSOUTPUT" to print the graph to an encapsulated postscript file:

	EPSOUTPUT="example.eps" $CMD ...

Prepend "SVGOUTPUT" to print the graph to an scalable vector graphics file:

	SVGOUTPUT="example.svg" $CMD ...
