Why Use This Radar Chart Maker
Instant Live Chart
The radar chart redraws as you type. There is no upload step and no waiting. Paste axis and value pairs from Excel, Google Sheets, or a CSV and the chart appears.
Compare Several Profiles
Add a second series in the optional box, or paste a table with a header row to overlay up to four series. Each one gets its own colour and a legend entry.
A Scale You Control
Leave the scale on Auto and the rings follow your data. Type a maximum such as 5, 10, or 100 to match a rating scale or a test score, so every chart you make uses the same rings.
Summary Stats Included
Under the chart you get the number of axes and series, the highest and lowest value, and the mean of the first series, plus a data table with every number.
Export and Share
Download a 2× PNG for slides and homework, or an SVG you can edit in any vector tool. Copy the image to your clipboard, or share a link that rebuilds the same chart with your data and settings.
Free and Private
Everything runs in your browser and your data is never uploaded to a server. No signup, no limits, no paywall.
What Is a Radar Chart?
A radar chart, also called a spider chart or web chart, plots several variables on axes that start from one centre point. Each value is marked on its axis and the marks are joined into a polygon. The shape shows at a glance where a profile is strong and where it is weak.
For a skills review, a product comparison, or a balanced scorecard, a radar chart puts the whole profile in one picture. This free radar chart maker gives you the chart, the summary numbers, and the table together.
- Radar Chart vs Bar Graph
- A bar graph compares values with more precision. A radar chart shows the overall shape of a profile and makes it easy to overlay two of them. For exact differences on one measure, use a bar graph.
- All Axes Share One Scale
- Every axis runs from zero at the centre to the same maximum at the edge. That works when all variables use the same unit or rating scale. If they do not, convert them to a common scale such as 0 to 100 first.
- Overlaying Series
- Two or three polygons on the same axes show where one profile beats another. Past four series the shapes cover each other, which is why this tool stops at four.
- When to Use a Radar Chart
- Skill assessments, product comparisons, survey scores by category, nutrition balance, and character or player stats. It suits five to eight axes measured on the same scale.
How to Make a Radar Chart Online
- 01
Paste your data
Type or paste one axis and value per line, like "Speed, 4". You need at least three axes. Copying two columns from Excel or Google Sheets works.
- 02
Add a series to compare
Fill the optional second box with another set of values for the same axes. For three or four series, paste a table whose first row is a header, such as "Feature, Product A, Product B".
- 03
Set the scale and title
Type a scale maximum to match your rating scale, or leave it on Auto. Add a title and pick the line colour for a single series.
- 04
Download and share
Export the finished chart as PNG or SVG, copy it to the clipboard, or share a link. The summary and data table below the chart list every value.
Tips for Better Radar Charts
Use Five to Eight Axes
With three or four axes the shape says little, and past ten the labels crowd. Five to eight axes give a shape people can read.
Put Every Axis on the Same Scale
Mixing a 1 to 5 rating with a 0 to 100 score flattens the smaller one. Convert everything to one scale before you plot it.
Fix the Maximum When Comparing Charts
If you make one chart per person or product, give them all the same scale maximum. Otherwise the same score lands on a different ring in each chart.
Order the Axes With Care
The area of the polygon changes with the order of the axes. Put related variables next to each other and keep the order the same across charts.
Limit the Overlays
Two or three series compare well. Beyond that, make one small chart per series with the same scale.
Higher Should Always Mean Better
If one axis is better when low, such as cost or error rate, invert it first. A mixed direction makes the shape misleading.
Radar Chart Concepts
Definition of a radar chart
A radar chart displays multivariate data on three or more axes that start from the same point and are spaced at equal angles. The value of each variable is plotted along its axis and neighbouring points are connected, forming a polygon.
What a radar chart tells you
- Strengths: the axes where the polygon reaches furthest.
- Weaknesses: the axes where it stays near the centre.
- Balance: a regular shape means even scores, a spiky one means uneven scores.
- Difference: where one overlaid profile sits outside another.
Limits worth knowing
The area of the polygon depends on the order of the axes, so do not read area as a total score. Values on different axes are also hard to compare with each other. When exact comparison matters, a bar graph does the job better.
Useful Calculations
Angle between axes
Angle = 360° ÷ number of axes
6 axes → 60° apart.
Distance from the centre
r = (value ÷ scale maximum) × radius
4 on a scale of 5 → 80% of the radius.
Mean score
Mean = Σ values ÷ number of axes
(4 + 3 + 5 + 4 + 2 + 5) ÷ 6 ≈ 3.83.
Rescale to 0–100
Score = (value − min) ÷ (max − min) × 100
3 on a 1–5 scale → 50.
Radar Chart Maker FAQ
Q01How do I make a radar chart from my data?
Paste one axis and value per line into the data box, separated by a comma, tab, or space (for example Speed, 4). With three or more lines the radar chart draws at once. Set the scale maximum, add a title, then download PNG or SVG.
Q02Is a radar chart the same as a spider chart?
Yes. Radar chart, spider chart, web chart, and star plot are names for the same chart type, with axes radiating from the centre and values joined into a polygon.
Q03How do I compare two or more series?
Enter the first series in the main box and the second in the optional second box, using the same axis names. For three or four series, paste a table with a header row such as Feature, Product A, Product B, Product C. The chart draws up to four series with a legend.
Q04How do I set the scale to 5, 10, or 100?
Type the number into Scale maximum. The outer ring takes that value and the inner rings divide it into five equal steps. If a data value is higher than the maximum you typed, the chart falls back to the automatic scale.
Q05How many axes can I use?
At least three, and there is no fixed upper limit. Five to eight axes read best. With many axes the labels start to crowd.
Q06How do I download or share the radar chart?
Click PNG for a raster image rendered at 2× for slides and documents, or SVG for a vector file you can edit in Figma, Illustrator, or Inkscape. Exported files carry a small kanaries.net credit in the corner, which the on-screen chart does not show. You can also copy the PNG to your clipboard, or click Share link to copy a URL that rebuilds your chart. The data travels in the link fragment and is never uploaded to a server.
Q07Is this radar chart maker free and is my data private?
Yes to both. The tool is free with no signup and no limits. It runs in your browser and your data is never uploaded to any server.
Q08When should I use a radar chart instead of a bar graph?
Use a radar chart to show the overall shape of a profile across several variables on one scale, or to overlay two profiles. Use the Bar Graph Maker when readers need to compare exact values.
