Bar Charts

Gaps between bars There should be gaps between the bars so that data is easy to read. Inconsistent labelling on each axis Each axis must be labelled in equal steps. This will help keep the bars at an equal width, and the height of each bar remains consistent. Not labelling axis The horizontal and vertical axes need to have data labels. Bars of equal width The bars need to be of equal width Using a bar graph for continuous data Bar charts should only be used for discrete or categorical data. A histogram should be used for continuous data.
