You don't need any of the quotes here, unless the arguments contain
spaces.

You have to use a backslash, i.e.
system("axis -lt \"Distribution\" -lx \"Staff\" -ly \"Month\" < cocomo-log | xplot");
Alternatively, you could use single quotes, i.e.
system ("axis -lt 'Distribution' -lx 'Staff' -ly 'Month' < cocomo-log | xplot");
