The Category describes the categories of a graphical representation. Categories of a chart are a discrete value range or an unsorted set of objects - such as January, February, March, and so on - that do not have a distance term and therefore have no relation to each other. In a vertical bar chart, the categories are displayed next to each other in columns with the categories on the x-axis and the values on the y-axis. This enables the user to compare individual categories – for example, the sales figures for each month of one year.
The following chart shows a business graphic of the vertical bar chart type with six categories and three data series. The six categories are displayed on the horizontal x-axis. The three data series are displayed as vertical columns for each category.
For example, the categories of a chart can represent the first six months, and each data series can represent a pharmaceutical company. The height of an individual column can indicate the revenue of a company in one month.
Unlike the simple category-based charts such as vertical bar charts, the more complex scatter charts and portfolio charts do not contain categories.
A pie chart represents all categories of a data series.
