- Add data series — click "Add Series" and enter a name and values for each category.
- Customize colors — use the color picker on each series to differentiate data visually.
- Export — download the radar chart as a PNG image to share with your team.
Why Radar Charts Matter
Radar charts excel at comparing multiple entities across several dimensions simultaneously. Unlike bar charts that show one variable at a time, radar charts reveal the overall "shape" of performance or characteristics, making patterns immediately visible.
They're particularly powerful for comparing team skills, product features, or performance profiles where you need to see strengths and weaknesses at a glance. The overlapping polygons make it easy to spot which entity leads or lags in each dimension.
Frequently Asked Questions
You can add as many categories as you need. For readability, 5 to 12 categories work best. Too few makes the shape hard to interpret, while too many can make labels overlap.
Values should be on a consistent scale. If comparing on a 1-10 rating, keep all values in that range. Normalize different metrics to the same scale for meaningful comparison across series.
Use radar charts when comparing profiles across multiple dimensions (e.g., skill sets). Use bar charts for direct single-variable comparisons. Radar charts work best with 3-12 dimensions and 2-5 data series.
