bar graph definition
A bar graph is a graph using rectangular bars to represent data points on a plane. Bar graphs are used for comparing amounts, or frequency of occurrence, of items in a set of data. Bar graphs allow comparison of groups of data, and enable generalizations of data quickly.Attributes.
Bar graphs have a title, axes, scale, label, and bars.
Details.
The title of a bar graph is optional, but provides a description of what the bar graph is measuring.
There are two axes in a bar graph. They are horizontal and vertical. The axis, representing each item of data, is the base. The other axis represents the amount, or frequency, of each item of data.
The labels of the bar graph describe what is being measured. For example, number of cars, production hours, or time in days are possible labels. Each axis uses a label.
The scale represents the quantity of measurement. Scale could be 1..2..3, or 10..20..30, etc. Each axis has a scale.
The bars, in the bar graph, represent data plotted using the horizontal and vertical axes. The bar height is the absolute value of the data from the base. The bar width is arbitrary.
