Preparing Effective Charts and Graphs
SECTION 2C: Be Honest

Just as graphs can clarify, simplify, and emphasize information, they can also distort, unnecessarily complicate, and hide information. Common practices that might mislead readers include omitting data, hiding data, not beginning axes scales at zero, manipulating elements in a photograph, and using color to misrepresent an item's importance. You are responsible for providing honest, clear, and accurate graphics.

Also, remember to acknowledge your source if you did not create or generate the data. Consult the style manual you are following for guidance on how to add a source statement in the caption of your graphic.

A graphic should be honest. The first bar graph below distorts data by using a three-dimensional display, an odd angle of viewing that blocks the third dimension of the first column, a vertical (y) axis starting at $60, and a bright color to emphasize the middle column. The second bar graph corrects these flaws.
