What makes a good bar chart?
Bar graphs have three key attributes: A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes.
What are the requirements for representing a bar chart?
A typical bar graph has a label or title, x-axis, y-axis, scales or increments for the axis, and bars. Some graphs may also have a legend that specifies what various colors represent, such as in a stacked bar graph. Bar graphs are ideal for comparing two or more values, or values over time.

- Labels: Both the side and the bottom of the bar graph have a label that tells what kind of data is shown.
- Bars: The bar is measures the data number.
