I need to make one graph showing changes in population for deer and wolves. I'm stuck because the deer scale would go by 500's. but the wolves are very small and would go by 2's! I have no idea how i can make my y-axis of my graph! any ideas?

Two options really.

1. Use two y axes, one on the LHS of the paper and one on the RHS of the paper. One runs from say 0-500 (deer) and the other runs from 0-2 (wolves)

2. Use the same LHS y axis and label the tickmarks 0-5, but put two labels on the axis, 'number of wolves' and 'number of deer/100'

Alternatively have two separate graphs one directly above the other so that they follow the same x-scale.
