What is an Area Chart?
An area chart is similar to a line chart but with the area below the line filled in with color. This filling emphasizes the magnitude of values over time and can make it easier to see the overall volume or quantity represented by your data.
Area charts are particularly effective when you want to highlight the cumulative total of values or show how different parts contribute to a whole over time. The colored area creates a visual weight that draws attention to the size of values, not just their changes.
There are two main types: standard area charts where areas may overlap, and stacked area charts where areas are placed on top of each other. Stacked area charts are great for showing how multiple categories contribute to a growing or shrinking total.
When Should You Use an Area Chart?
✓ Best Used For
- •Emphasizing the magnitude of change over time
- •Showing cumulative totals or volume
- •Visualizing part-to-whole relationships over time (stacked)
- •Highlighting the area between values and the axis
- •Making trends more visually prominent
✗ Avoid When
- •You have multiple overlapping series (they become hard to read)
- •Precise value reading is important (the filled area can obscure exact points)
- •You have discrete, categorical data (use a bar chart)
Pro Tip: Area charts add visual weight to line charts, making them feel more substantial. Choose an area chart when the size or volume of the data is as important as the trend. Use a line chart when you need cleaner visibility of exact values and intersections.
How to Format Your Data for Area Charts
Step-by-Step Guide
- 1Structure your data like a line chart: time/category column and value column(s)
- 2Order your data chronologically from earliest to latest
- 3Use a single value column for simple area charts
- 4For stacked areas, include multiple value columns (each becomes a layer)
- 5Ensure all values are positive for best visual results
💡 Tips for Better Results
- • Area charts work best with 1-3 data series; more can become cluttered
- • Consider using transparent fills if series overlap
- • Stacked area charts work best when showing contributing parts to a total
- • Large value differences between series can make smaller series hard to see
