Radar Chart
Compare entities across multiple variables with Radar Charts (Spider Charts). Visualize profiles and performance shapes.
Radar Charts (or Spider Charts) are designed to compare multiple variables perpendicular to a central point. They are excellent for visualizing the "profile" or "shape" of a dataset, such as comparing the skills of an employee (Communication, Coding, Design) or the features of a product (Price, Speed, Battery, Camera).
Edilitics renders these complex polygonal charts using a point-and-click interface, ensuring that your multi-dimensional comparisons are based on trusted, governed metrics.
When to Use a Radar Chart
| Use Case | Why This Chart Works |
|---|---|
| Skill Assessment | Visualize an employee's strengths across 5+ competencies. |
| Product Comparison | Compare Product A vs Product B across Specs, Cost, and Rating. |
| Performance Audit | Marketing Channels: Compare ROI, Reach, and Engagement in a single shape. |
| Outlier Shape | Spot if a process is "balanced" (round shape) or skewed (spiky shape). |
Chart Configuration in Edilitics
Inputs Required
| Data Type | Required Count | Description |
|---|---|---|
| Dimensions (Columns) | 1 | Categorical field defining the radar axes (corners). |
| Metrics (Rows) | 1 - 10 | Numerical values plotted as series on the radar web. |
How to Configure a Radar Chart
- Select "Radar Chart" from the Chart Library.
- Define Axes:
- Drag your indicator category to Radar Indicator.
- Drag your metric to Value.
- Compare Groups (Optional):
- Drag a second dimension to Series to overlay two polygons (e.g., "This Year" vs "Last Year") for direct shape comparison.
- Formatting:
- Shape: Choose between Polygon (straight lines) or Circle (curved lines) for the grid.
- Area Style: Add transparency to the fill color to see overlapping shapes clearly.
Feature Highlights
Intelligent Scaling
- Edilitics automatically normalizes scales if comparing metrics with vastly different ranges (optional), or enforces a shared maximum (e.g., 0-100%) for fair comparison.
Overlap Management
- When comparing multiple entities, use semi-transparent fills (alpha blending) to show where the profiles intersect versus where they diverge.
Interactive Legend
- Toggle specific series on/off to isolate a single profile for focused analysis without removing it from the configuration.
Tooltip Detail
- Hovering over a vertex shows the specific value for that indicator, ensuring precision alongside the visual overview.
Best Practices for Radar Charts
| Practice | Why It Matters |
|---|---|
| Limit Variables | Use 3-8 variables. Less than 3 is a line; more than 8 becomes a messy web. |
| Consistent Scale | Ideally, all axes should share a scale (e.g., 0-10 or 0-100%) to make the shape meaningful. |
| Comparable Entities | Only overlay entities that make sense to compare directly (e.g., two similar products). |
| Avoid Chronology | Radar charts imply a cycle or equality; do not use them for linear timelines (use Line charts instead). |
How Edilitics Is Different
Unlike fragile spreadsheet-based radar charts, Edilitics treats them as dynamic visualizations:
-
Dynamic Schema Adaptation: If a new skill/variable is added to your data, the radar chart automatically updates with a new axis.
-
Self-Maintaining Profiles: Your competency profiles stay current as the underlying data evolves.
-
Interactive Legends: Toggle specific series on/off to isolate and compare profiles.
-
Governed Metrics: All axis values are derived from validated datasets, ensuring consistency.
This ensures your performance fingerprints effectively maintain themselves.
Radar Charts provide a fingerprint of performance. With Edilitics, you can instantly see if your business, product, or team is "well-rounded" or excelling in a specific niche.
