Bar chart graphic
A bar graph (or bar chart) displays data using rectangular bars. One axis of a bar chart measures a value, while the other axis can portray a variety of categories. When the data is plotted, the chart presents a comparison of the categories. A bar chart is a graph with rectangular bars. The graph usually compares different categories. Although the graphs can be plotted vertically (bars standing up) or horizontally (bars laying flat from left to right), the most usual type of bar graph is vertical. A bar graph (also known as a bar chart or bar diagram) is a visual tool that uses bars to compare data among categories. A bar graph may run horizontally or vertically. The important thing to know is that the longer the bar, the greater its value. Bar graphs consist of two axes.
