Barcelona Field Studies Centre

Polar Chart Creator

This Polar Chart Maker creates circular charts to display values based on distribution and frequency of angles data. Axes radiate out from the centre point of the circle like spokes on a wheel. Each axis represents an angle (from 0 to 359 degrees), with values increasing outwards. The data for each angle are plotted as a point on the corresponding axis and points are connected to form a shaded polygon.

Polar charts are commonly used in physical geography fieldwork to display the number of pebbles orientated along a particular compass bearing, or the number and direction that cirques or corries face.

Enter your data in the calculator below, in clockwise order of size. Click the 'Calculate' followed by 'Open Polar Chart' buttons and your Polar 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.
