INTRODUCTION ( Click here for dictionary )
Bar charts are generally useful for showing overall trends and comparisons. The most common ones are horizontal and vertical bar charts. The other types are multiple bar charts and subdivided bar charts.
1. Vertical Bar Chart ( Click to see Sample 1 and Sample 2 )
2. Horizontal Bar Chart ( Click to see Sample 1 and Sample 2 )
3. Multiple Bar Chart ( Click to see Sample 1 and Sample 2 )
4. Subdivided Bar Chart ( Click to see Sample 1 and Sample 2)
Vertical and horizontal bar charts are useful in comparing differences in quantities. Multiple bar charts, on the other hand, make it possible to compare two or three variables within a single bar. If you need to show how different facts (components) contribute to a total figure, then the subdivided bar chart is desirable. A legend is provided in the multiple and subdivided bar chart as a key to the variables, facts or components.
