Variable-form Pie
Variable-form pies use equal-angle wedges and encode values through radius and top shape. This is a Plus feature; standard 2D and 3D pies remain Free.
Prepare the data
Prepare one category column and one non-negative numeric column. Use a small number of categories and retain value labels for precise reading.
This practice dataset is not the source of the screenshot. Keep category and value in separate columns; check missing values, negative values, and duplicate categories.
| Category | Value |
|---|---|
| Sample A | 40 |
| Sample B | 28 |
| Sample C | 18 |
| Sample D | 12 |
| Sample E | 8 |
| Sample F | 4 |
Interpretation and pre-export checks
- Equal-angle wedges do not encode proportions through angle. Percentage labels still come from the numeric total.
- With uniform radius, wedges have equal visible area; values are conveyed by labels only.
- Linear area mapping uses a square-root radius transform. Minimum radius affects the visual baseline; do not read visible petal area directly as a percentage.
- Linear radius mapping emphasizes differences. Value-driven 3D depth amplifies them further; use uniform depth or a bar chart for precise comparison.
Adjustable settings
These are the common settings for this plot type. For detailed line, marker, axis, legend, and font styling, see Styling.
- Top Shape: Sector / Rounded Petal
- Radius: Uniform / Encode Value
- Value Mapping: Linear Area / Linear Radius
- Minimum Radius
- Labels, leader lines, and palette
- 3D Depth: Uniform / Encode Value
