When You Need More Than Two Datasets
Sometimes you have more than just two categories to compare over time. Maybe you're looking at traffic from organic, direct, referral, and social sources. Or revenue across four different product lines. A multi-area chart handles these scenarios beautifully.
This chart type gives you two powerful ways to look at your data. Overlapping areas let you compare the magnitude of each series against the others directly. Stacked areas put the series on top of each other, letting you see the total cumulative volume while still seeing the individual contributions.
With this free tool, you can build multi-series area charts right in your browser. Add or remove series dynamically, change colors, toggle stacking on and off, and download the finished chart in seconds.
How to Create a Multi-Area Chart
- 1Set your categories. Enter the shared X-axis labels (like months, quarters, or years). Alternatively, upload an Excel file where column A has categories and subsequent columns have your series data.
- 2Add data series. Click "Add Series" for each dataset you want to plot. Give each one a name, select a distinct color, and enter the Y values. The chart builds itself as you type.
- 3Customize and export. Toggle "Stacked Areas" to see the cumulative total, adjust fill opacity, curve style, and download as PNG, JPEG, or SVG for your presentations and reports.
Common Use Cases
Revenue by Product Line
See how different products contribute to total sales over time. Stacking the areas instantly shows total company revenue.
Multi-Channel Traffic
Compare organic, direct, paid, and social traffic volume. Overlaying the areas shows which channel is driving the most volume month by month.
Budget Allocation
Track spending across multiple departments (marketing, sales, R&D). Stacking helps visualize total budget burn rate.
Energy Sources
Plot power generation from solar, wind, hydro, and fossil fuels. A stacked chart perfectly illustrates the energy mix over time.
Patient Demographics
Visualize hospital admissions broken down by age groups or regions. Easily spot trends in specific demographics.
Enrollment by Major
Track student enrollment across different academic departments to plan resource allocation and faculty hiring.
Best Practices for Multi-Series Areas
- Use stacking for totals. If the individual parts add up to a meaningful whole (like revenue from different regions), use the "Stacked Areas" toggle. It's much easier to read the total value.
- Avoid stacking non-additive data. Never stack averages, percentages, or distinct metrics (like temperatures and rainfall). Only stack values that can logically be summed.
- Limit the number of series. More than 4 or 5 overlapping areas become a muddy mess. Even when stacked, too many thin slices make the chart illegible. If you have 10 series, consider grouping smaller ones into an "Other" category.
- Manage opacity carefully. For overlapping (non-stacked) areas, you need a low fill opacity (around 30%) so the areas behind remain visible. If stacked, you can use 100% opacity safely.
Comparing Chart Types
| Chart Type | Use Case | Key Feature |
|---|---|---|
| Multi-Area (Overlapping) | Comparing multiple individual volumes | All series start at zero axis |
| Multi-Area (Stacked) | Showing parts of a whole over time | Series are stacked, showing cumulative total |
| Multi-Line Graph | Comparing pure trends | No fill, less cluttered for 4+ series |
| Stacked Bar Chart | Comparing discrete totals | Not continuous, emphasizes specific periods |
Frequently Asked Questions
How do stacked area charts work?+
In a stacked area chart, instead of each series starting from the bottom (zero), they start from the top of the previous series. This means the top line of the entire chart represents the combined total of all your data series at that point in time. It's excellent for visualizing part-to-whole relationships over time.
How many series can I add?+
Technically, you can add as many series as you want using the "Add Series" button. However, for readability, we recommend sticking to 3 to 5 series. Any more than that, and the chart becomes visually overwhelming and difficult to interpret.
Can I import from Excel?+
Yes. Use the "Import Excel" button. Format your file with X-axis categories in Column A, and then use Column B, Column C, etc., for your different series data. The tool will automatically create the necessary number of series.
What is the best opacity setting?+
If you are using overlapping (non-stacked) areas, set the opacity low (20% - 40%) so you can see where the areas overlap. If you enable "Stacked Areas", you can increase the opacity to 80% or 100% since no areas are hidden behind others.
How do I change the colors?+
Each series in the "Data Series" section has its own color picker. Click the color swatch next to the series name to choose a specific color. For best results, use distinct, contrasting colors.
Is my data secure?+
Yes, 100%. The chart generation happens entirely within your web browser. No data is ever uploaded to our servers, stored, or tracked.
