Radar Chart Overlay Maker

This Radar Chart Overlay Maker places multiple observations in a single circular graph by displaying two polygons, overlaying them opaquely.

Radar chart overlays are commonly used in geography fieldwork to analyse data from two or more contrasting field study sites. Differences in the polygon shapes reflect changes in the underlying category values. The extent of overlap helps clarify the differences and similarities between the sites.

This radar chart can display values for a single category based on distribution and frequency of alphabetic compass directions. Radar Overlay Chart axes labels are non-numeric and if a 0-360 degrees numeric layout is required, our Polar Chart Overlay Maker should be used.

Enter your data in the calculator below. Click the 'Calculate' followed by 'Open Radar Chart' buttons and your radar overlay chart will open in a new window. A menu appears above the chart offering several options, including downloading an image. Hover over the chart to display the data.
