A bar graph, also known as a bar chart, is a graphical representation of data using rectangular bars or columns of equal width but varying heights. The bars can be plotted vertically or horizontally, and they are used to compare and contrast different types of data. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value. Bar graphs are commonly used in business and financial analysis to display often complicated data, as they can convey information quickly and effectively.
Some key properties of bar graphs include:
- The bars are of equal width and varying height.
- The gap between one bar and another should be uniform throughout.
- They can be either horizontal or vertical.
- They are used to display categorical data.
- They can be used to show the relationship between two or more sets of data.
Bar graphs can be grouped or stacked to represent related sets of data. They are a visual representation of data and are used to show the distribution of different types of data, such as the favorite type of movie or the nicest fruit.
