1. Small Data Sets

Grouped Graph:

• Best when comparing a few categories side-by-side.
• Effective if you want to clearly see individual values without focusing on cumulative or proportional contributions.

Stacked Graph:

• Useful if there’s a need to show part-to-whole relationships even with few data points.
• Works well for cases where each category’s contribution matters to the total.

100% Stacked Graph:

• Often unnecessary unless you specifically need to show proportions of each category.

1. Medium Data Sets

Grouped Graph:

• Can work if the data series and categories are distinct but may start to look crowded.
• Best when exact comparisons are important and the number of bars or data points is manageable.

Stacked Graph:

• Effective for showing both total and part-to-whole contributions without excessive clutter.
• Helps show cumulative values without overwhelming the viewer, making it suitable for moderate data volume.

100% Stacked Graph:

• Works well for focusing on proportions and relative comparisons, especially if the goal is to communicate percentages across categories.
