and then plot them all on one graphics window
# Am I working in the right direction- I have just discovered lists (I
know I know, I am a little slow)

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods. We are mammals, and have not exhausted the
annoying little problems of being mammals.
