About this tool
The Radar Chart Generator draws a polygon-grid spider chart for any number of axes and up to eight series, either scaling each axis to its own maximum or to one shared maximum so the shapes stay comparable. Fill opacity, dot markers, ring count and colours are all adjustable, and the table under the chart shows every entered value next to its normalised percentage. All rendering and PNG export happen in your browser.
