Polar Area Chart Maker

This Polar Area Chart Maker creates circular charts with segments that radiate outwards at the same angle from a central point. The arc radius and length of each segment increases in proportion to the quantity it represents and a scale shows the segment values.

Polar Area diagrams are useful for displaying fieldwork data where a values scale helps to provide context for comparisons.

Enter your data in the calculator below. Click the 'Calculate' followed by 'Open Polar Chart' buttons and your Polar Area Chart will open in a new window. Hover over the chart to display the data and right-click to save the image.
