- Keep in mind that the x-axis (horizontal) is displaying time, based on months.
- There are two y-axes (vertical). The far left shows average temperature in degrees Fahrenheit (ºF), whereas the far right shows average temperature in degrees Celsius (ºC).
- The dotted line graphs the average temperature for New York, whereas the solid line graphs the average temperature for Miami (found in the graph legend near the top).
- The x-axis here also shows time, in years.
- There are again two vertical, or y-axes. The far left axis shows temperature in degrees Fahrenheit (ºF), whereas the far right axis shows the temperature departure from average (or anomalies) in degrees Fahrenheit (ºF).
- Red areas mean the temperatures above average (17.3ºF, noted in the upper portion of the graph), whereas blue areas indicate below average temperatures.
- As with the other two graphs, the x-axis (horizontal) shows time, but in this case without any specific units.
- The y-axis (vertical) is increasing as we move up the graph, but doesn't convey what the units are.
- We also don't know what the green line and blue line are graphing.
- All we know is that they are both increasing with time, and that the green line is increasing exponentially.
