Grouped Area Chart
A grouped area chart, also known as a multi-series stacked area chart, takes the standard area chart a step further by adding a grouping variable. This enables you to visualize trends and compare them across different categories simultaneously.

Good choices for Group Axis
- Categorical values
- Stacked area: Similar to a regular stacked area chart, multiple lines and shaded areas are layered on top of each other.
- Grouping dimension: An additional variable in your data set determines the grouping. Each stack of area segments represents a separate category or group.
- Colors and patterns: Different colors or patterns are typically used for each group’s stacked area, ensuring visual distinction and facilitating comparisons.
- Axes: Two axes form the chart’s base: Horizontal axis (X-axis): Represents the continuous variable (often time). Vertical axis (Y-axis): Represents the values being measured.
When to use a Grouped Area Chart
- Compare trends across groups: See how the trends of multiple datasets differ or evolve within each category.
- Identify group-specific patterns: Analyze unique trends and variations within each group over time.
- Understand cumulative totals: Observe how the value for each group accumulates over time and compare relative contributions.
