What is a Bar Chart?
A bar chart is a graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally.
Types of Bar Charts
- Grouped Bar Charts: Compare values across categories for multiple series
- Stacked Bar Charts: Show the composition of each category
- 100% Stacked Bar Charts: Display the percentage contribution of each value to the total
Interpreting Bar Charts
When interpreting a bar chart, consider the following:
- The height or length of each bar represents its value
- Compare the relative sizes of bars to understand differences between categories
- For grouped or stacked charts, look for patterns across groups
- Pay attention to the scale of the value axis to avoid misinterpretation
