That depends all on what you are plotting. If you are after the amount of work it was to go from uneducated to educated then a shallow slope is preferable (with amount of work on the y axis, and degree of educated on the x axis). Wether a shallow or steep slope is preferable is all dependent on what one is actually measuring. Cheers Tommy -- http://mail.python.org/mailman/listinfo/python-list
