More complex graphs

The graphs from 4.1 were all simple. They looked at one column or row of data. In this section, we will look at multiple columns or rows of data.

One of the important things this section emphasizes is to use labels on your graphs.

Please do hands on exercise 4.2 pages 162 - 168. Please make sure that your name and homework 18 are on this worksheet somewhere, print as instructed on page 167, and turn it in as homework 18.
