Excel Stacked Line Charts are an excellent way to visualize cumulative data trends over time. This tutorial by The Coding College will guide you through creating and using Stacked Line Charts effectively, ensuring your analysis stands out and benefits users.
What is a Stacked Line Chart?
A Stacked Line Chart is a variation of the Line Chart where multiple data series are layered on top of each other, showing how each series contributes to the cumulative total. It’s ideal for understanding the composition of data over time.
When to Use Stacked Line Charts
- Cumulative Trends: Analyze how different categories contribute to a total.
- Proportional Analysis: See how individual datasets grow in relation to others.
- Time-Series Data: Ideal for datasets involving time, such as quarterly sales or annual revenue.
Key Features of Stacked Line Charts
- Layered Representation: Each line represents a cumulative value.
- Time-Based Visualization: Works best for sequential data like months, quarters, or years.
- Easy Comparisons: Helps compare contributions of multiple datasets at once.

Benefits of Stacked Line Charts
- Cumulative Insights: Understand the total growth over time.
- Proportional View: See how each dataset contributes to the whole.
- Clear Comparisons: Ideal for comparing multiple categories simultaneously.
Example: Monthly Product Sales
Using the data example above, a Stacked Line Chart will show how the sales of Product A, Product B, and Product C grow and contribute to the total sales each month.
Customizing Stacked Line Charts
- Colors: Use distinct colors for each series to improve visual clarity.
- Gridlines: Add gridlines for easier value interpretation.
- Markers: Use markers to emphasize data points.
- Data Labels: Display specific values for enhanced detail.
Best Practices for Stacked Line Charts
- Avoid Clutter: Limit the number of data series for clear visualization.
- Focus on Trends: Highlight significant patterns or insights.
- Use Legends Wisely: Ensure the legend is easy to understand.
Common Applications
- Sales Performance: Track contributions of different products or regions.
