Use a radar chart
Use a radar chart to compare the overall profile of one or more series across the same set of metrics. The polygon shape makes relative strengths and weaknesses easy to scan.

How to make a radar chart
- 1
Add metrics and series
Enter metric names in the first column, then add one or more numeric series with clear headers.
- 2
Review the shared scale
Check that the metrics use comparable units and confirm the automatically selected range.
- 3
Customize and export
Adjust the fill, grid, legend, labels, and colors, then download the finished radar chart.
What is a radar chart?
A radar chart places each metric on an axis radiating from a shared center. Values are connected into a polygon, making the overall profile of each series visible at a glance. Radar charts are also called spider charts or web charts.
This radar graph maker uses the first text column for axis labels and turns every numeric column into a separate series. Real column headers appear in the legend, so teams, products, candidates, or scenarios remain clearly identified.
Use the online radar chart maker to paste data or import CSV and Excel files, then customize and export the chart directly in your browser.
Example radar chart data
Put metric names in the first column and one comparable numeric series in each following column.
| Metric | Team A | Team B |
|---|---|---|
| Speed | 80 | 70 |
| Quality | 90 | 85 |
| Cost | 65 | 78 |
| Support | 88 | 82 |
| Reliability | 92 | 89 |
Radar Chart vs Bar Chart
Radar and bar charts can compare the same measurements, but they emphasize different aspects of the data.
Use a bar chart
Use a bar chart when precise value comparison and straightforward ranking matter most, especially when there are many categories or readers need to judge small differences.
When to use a radar chart
Radar charts work best when a small set of comparable metrics describes an overall profile.
Team or candidate profiles
Compare strengths across skills, competencies, or performance measures.
Product comparisons
Contrast products or plans across shared attributes such as quality, cost, and support.
Before-and-after reviews
Show how a profile changes across the same assessment criteria.
How radar scales work
Every axis in a radar chart shares one scale so the shape remains comparable across metrics and series.
Percentage-like values
When every value falls between 0 and 100, the chart uses a consistent 0–100 scale.
Other numeric ranges
For larger values, the radar chart generator chooses a rounded maximum above the highest observation.
Comparable units matter
Use metrics with compatible meanings or normalize them first; otherwise the polygon shape can give a misleading comparison.

Radar chart maker FAQ
Answers about arranging metrics, comparing series, and choosing a readable scale.
Is this radar chart maker free?
Yes. The free radar chart maker requires no signup and exports clean PNG or SVG files without a watermark.
How should I arrange radar chart data?
Use a text column first for metric names. Add one or more numeric columns after it; each numeric header becomes a legend label and radar series.
Can I compare multiple series?
Yes. The spider chart maker supports multiple numeric series, which are drawn on the same metric axes for profile comparison.
How does the chart choose its scale?
Values between 0 and 100 use a shared 0–100 scale. Other ranges use a sensible rounded maximum based on the largest value in the dataset.
What happens when a value is missing or invalid?
The editor shows an actionable message identifying the missing or invalid cell instead of drawing a misleading chart.
How many metrics should a radar chart contain?
The chart still renders, but the editor warns when there are more than 12 metrics because labels and polygons can become difficult to read.
Can I import radar data from Excel or CSV?
Yes. Paste a spreadsheet table or upload CSV and XLSX files. Your data remains in the browser.
