The question asks to identify any misrepresentation issues in the graph. The graph shows the air temperature in two test chambers controlled by two different HVAC controllers over a 24-hour period, along with the target temperature.
There are a few misrepresentation issues in the graph:
- The axes are not labeled. This makes it difficult to interpret the graph, as it is not clear what the units on the x- and y-axes are.
- The target temperature line is not drawn to scale. The target temperature is supposed to be 68 degrees Fahrenheit, but the line on the graph is drawn at approximately 67.8 degrees Fahrenheit. This makes it appear as if the controllers are closer to meeting the target temperature than they actually are.
- The tick marks on the x-axis are not evenly spaced. This makes it difficult to accurately compare the temperature readings at different times of day.
In addition to these misrepresentation issues, the graph could also be improved by:
- Adding a title. The graph should have a title that clearly states what it is showing.
- Labeling the data series. The data series for each controller should be labeled so that it is clear which line corresponds to which controller.
- Adding a legend. The legend should explain the symbols and colors used in the graph.
