About the Radar Chart Maker
A radar (or spider) chart puts several criteria on spokes around a centre and draws each item as a shape, so strengths and gaps show at a glance: a candidate strong in leadership but weaker in design, a phone with the best camera but the shortest battery life, this year’s ratings against last year’s. Paste a table with the criteria in the first column and a column of scores for each item — or the items in rows and a column per criterion — and get the chart.
Use one shared scale when every criterion is scored the same way (0–10, 1–5, %), or a scale per axis when they are measured in different units, and mark the criteria where lower is better (price, weight, waiting time) so their best end points outwards. Draw filled or outlined shapes, polygon or circle gridlines, values at the points, or one small chart per item. Everything is drawn in your browser.
How to use it
- Paste your table into Your data, or open a CSV or Excel file: criteria in the first column and one column of scores per item, or one row per item and one column per criterion.
- Check Criteria are (in the rows or the columns) and tick the items to show under Items shown.
- Choose the Scale: shared, with the axes from 0 (or a value such as 1) to a maximum such as 10, or one scale per axis; tick the criteria where lower is better.
- Pick filled or outlined shapes, the gridlines, the colours and whether values are written at the points, or show one chart per item.
- Add a title and a note, then download the chart as PNG or SVG and the scores as CSV — with a Pro pass, or after unlocking this result; without one the page shows a free preview.
Examples
Skill Asha Ravi Communication 8 6 Coding 7 9 Design 6 5 Testing 7 8 Leadership 9 5 Documentation 8 6
Asha reaches further on communication, design, leadership and documentation, Ravi on coding and testing; overall 75% and 65% of the axes
Phone Price ($) Battery (h) Camera (MP) Model A 799 22 48 Model B 649 26 50 Model C 499 19 64
With a scale per axis and Price marked “lower is better”, Model C’s shape reaches furthest on price and camera, Model B’s on battery
Rating This year Last year Service 4.4 3.9 Price 3.6 3.8 Speed 3.9 3.1
Axes from 1 to 5 in 4 rings; this year is ahead on service and speed and slightly behind on price
Common uses
- Comparing candidates, players or teams on the same set of skills.
- Comparing products on price, performance and features for a buying guide or a pitch.
- Showing survey or review ratings by category, this year against last year.
- Self-assessment wheels: where you are now and where you want to be.
- Balanced scorecards and maturity models scored on a fixed scale.
Shared scale or a scale per axis
With a shared scale, every spoke runs over the same range, so 8 on one criterion is as far out as 8 on another; the rings are labelled along the top spoke. Set where the axes start (0, the smallest score, or a value such as 1 for a 1–5 rating) and where they end (10, 5, 100); the range is then cut into exactly as many rings as you choose.
With a scale per axis, each spoke runs over its own range, written under its name (“16 → 26”), so criteria in different units — dollars, hours, grams — can share one chart. Starting from the smallest score moves the centre a quarter of the spread below it, so the weakest item is not a point in the middle. Shapes then show how items rank on each criterion, not how large the values are.
When lower is better
For a price, a weight or a waiting time, a smaller value is better. Tick it under Lower is better and its spoke is turned round: the best (smallest) value is at the tip, so a larger shape always means better. The axis says “lower is better”, and the table marks the criterion. The overall row in the table averages each item’s position on all the axes (0% at the centre, 100% at the tip), which gives a single score that counts every criterion equally.
Reading a radar chart fairly
Compare items point by point along each spoke. The area of a shape is a poor measure: it grows with the square of the scores and changes with the order of the criteria around the circle, so two items with the same scores in another order can look very different. Put related criteria next to each other, keep the number of items small (two to four overlap well; use one chart per item for more), and when exact comparisons matter, show the same table as a grouped bar graph.
Limitations
- From 3 to 12 criteria and up to 10 items; a chart with more is very hard to read.
- A missing score leaves its point out, and the outline is broken there.
- Value labels that would cover another label are left out; the table has every score.
- The PNG uses your device’s system font; the SVG names common system fonts, so text can look slightly different on another computer.

Frequently asked questions
What do I get without a pass?
Without a pass, Radar Chart Maker shows the radar chart at preview size (up to 640 pixels) with a watermark, and the first rows of its table (up to 10). Until you unlock it, the result can’t be downloaded or copied. A Pro, Premium or Ultimate pass, a one-time payment that never renews, unlocks the full result. The pricing page lists the passes and their prices.
How do I make a radar chart from Excel?
Put the criteria in the first column and one column of scores per item (with the items’ names in the header row), copy the cells and paste them into Your data, or open the file. A table with one row per item and a column per criterion works too.
What is the difference between a radar chart and a spider chart?
Nothing: both names — and “web chart” or “star plot” — mean the same chart with one spoke per criterion. Gridlines drawn as polygons look like a spider’s web; circles are the other common style.
Can I compare criteria with different units?
Yes: choose a scale per axis. Each spoke then runs over its own range, shown under its name, and criteria where lower is better can be turned round so that bigger shapes always mean better.
How is the overall score worked out?
For each item, every score is placed on its axis as a share of the axis range (0% at the centre, 100% at the tip, turned round where lower is better), and the shares are averaged. Every criterion counts equally.
Is my data uploaded?
No. The chart is drawn in your browser, and files you open stay on your device.
