Key Takeaways:

  • Graphs can be powerful tools for conveying data, but they can also be manipulated to mislead and distort information.
  • Misleading graphs often misuse visual proximity, manipulate data, and omit important details, making it crucial to approach them with skepticism.
  • Several examples of misleading Covid-19 graphs highlight the different tactics employed, such as incorrect y-axis intervals, flawed data representation, and deceptive time-traveling effects.
  • It’s essential to critically analyze graphs, consult accurate data, and follow best practices when creating or interpreting them.

An Act of Omission

Graphs have long been used as a means to influence and persuade audiences. While they can be effective tools for visualizing data, they can also be employed to deceive and mislead. This article delves into the world of misleading graphs, specifically focusing on examples related to the Covid-19 pandemic.

One prominent tactic used in misleading graphs is the manipulation of visual elements. For instance, graphs may misuse visual proximity to create a distorted perception of data. One such example involved a graph shared on Twitter, which featured an uneven y-axis interval. By flattening the graph, it gave the false impression of a less significant change. Comparatively, recreating the graph with correct intervals revealed a more accurate representation of the data. This manipulation not only distorts the information but also obscures the true magnitude of the depicted phenomenon.

Another technique employed in misleading graphs is the manipulation of data. In the context of Covid-19, certain graphs appeared to show declining cases when, in reality, the opposite was true. The issue stemmed from flawed data collection and interpretation. In one instance, testing restrictions in Florida led to limited testing availability. Moreover, negative results were counted multiple times, skewing the percentages presented in the graph. The existence of conflicting data sources further complicated the interpretation, with different individuals drawing divergent conclusions from the same figures. This highlights the importance of accurate data collection and transparency to ensure the reliability of graphs.

Georgia’s Trends are Just Peachy

Graphs can be misleading not only in their content but also in their presentation. In a particularly egregious example, the State of Georgia was accused of indulging in time travel through graph manipulation. The graph showcased a peculiar “staircase” effect, with dates hopping back and forth along the x-axis. The deliberate rearrangement of colored bars further added to the confusion. This manipulation of the timeline creates a distorted narrative, making it challenging to interpret the data accurately. The incident emphasized the need to scrutinize the axes, labels, and overall structure of a graph to ensure its integrity.


When it comes to graphs, skepticism and critical analysis are essential. While they can be valuable tools for visualizing data, they can also be employed to deceive and mislead. It is crucial to be aware of the various tactics used in misleading graphs, such as misusing visual proximity, manipulating data, and distorting timelines. By approaching graphs with a critical eye, consulting accurate data, and adhering to best practices, we can navigate through the sea of misinformation and make informed decisions based on reliable information.

Remember, not everything is as it appears on a graph.
