How do I make a radar chart online?

Enter your axes as a comma-separated list, then add one or more series whose values line up with the axes. Set a scale max, and the radar chart updates live. Then download a PNG or SVG. There's no signup and no watermark.

Can I overlay multiple series?

Yes. Add more than one series and each draws its own colored polygon with a legend, which is ideal for us-versus-competitor or you-versus-benchmark comparisons. Each series' values must line up with the axes in order.

Can I download the radar chart as PNG or SVG?

Yes, both are free with no watermark. SVG gives you a crisp vector file you can scale or edit; PNG is a high-resolution raster ready for a slide, report, or social post.

Can I generate radar charts automatically via an API?

Yes. Save your chart as an Imejis template, mark the radar component dynamic, and POST fresh axes and series to one endpoint to render the same chart on every call. It's the only radar tool with a matching image API.

Is the radar chart maker free?

Yes, it's completely free in the browser with no signup and no watermark, and PNG and SVG downloads are unlimited. The matching image API has a permanent free tier of 100 calls per month.

What is a radar chart?

A radar chart, also called a spider chart, plots several variables on axes that radiate from a center and draws one polygon per data series. It's the clearest way to compare profiles across three to eight dimensions at once, which makes it perfect for scorecards and side-by-side comparisons.

How to make a radar chart

1Set your axes. Enter the axis labels as a comma-separated list. Three to eight axes read best.
2Add a series. Add one or more series, each with a name, a color, and values that line up with the axes in order.
3Set the scale. Pick a scale max, such as 100, so charts stay comparable, then choose a light or dark background.
4Download PNG or SVG. Click download for a high-resolution PNG or a crisp, scalable SVG. No watermark and no signup.
5Automate with the API (optional). Save it as an Imejis template and generate the same chart from live data on every API call.

What is a radar chart used for?
