Data in everyday life:
Charting gas prices, profits in multi-line form

With gas prices moving steadily upward, CHARTrunner creates a chart that documents average gas price percentage increases (by quarter), along with average profit percentage increases of the biggest oil companies. A multi-line chart such as this one can help show trends for more than one source of data. (Source for gas prices) (Oil companies' profits source from quarterly reports)
