The one's I've used personally, were just two lines on a single
chart.........one line would be the accumulated continuing cost as to the
way things are done now, starting low at the left and proceeding upward and
to the right........... and the second would start high on the left, with an
initial tooling or equipment investment, then it's line would proceed to
drop toward zero from left to right.......where they cross is the "break
even point".......
