The bar chart shows bathing-suit revenue in New York City during the first six months of 2012, while the line graph presents average monthly temperatures. Revenue is measured in hundreds of thousands of US dollars and temperature in degrees Fahrenheit.
Overall, revenue rose to a peak in April before falling sharply. Temperatures, by contrast, dipped slightly in February and then increased through June. The warmest month therefore did not coincide with the highest revenue.
In January, revenue was approximately 100 units on the stated scale, compared with around 125 in February and 150 in March. It then climbed substantially to about 290 in April, the highest figure shown. Thereafter, revenue dropped to roughly 80 in May and around 20 in June, its lowest level in the period.
Average temperatures followed a different pattern. They fell slightly from about 31°F in January to 30°F in February, before rising to 38°F in March and 49°F in April. The upward trend continued in the final two months, reaching approximately 59°F in May and 65°F in June, despite the marked decline in revenue.
