Misleading Graphs

Misleading graphs are sometimes created to intentionally misrepresent data. This is usually done in order to focus a reader’s attention on a specific trend or pattern.

It is important to always check the scale of a graph before inferring any message from the graph that could lead us to misinterpret the data.

Key components that should be present in a graphical display are: Horizontal axis, vertical axis, clear data lines or distinct bars, and a color legend.

Color

It is important to use good design principles when using color to communicate information. The color in a graph can be used inappropriately and can potentially lead to the misinterpretation of a graph.
