Graphs where made using gnuplot and with a lot of help
from the shell script
gengnuplot.sh which
is available
here.
Results
Note: This one looks different because gnuplot would not work right
with hidden
surfaces turned on. So on the above graph hidden surfaces is
turned off. I believe
gnuplot failed because the values in the graph are almost the same.
