Pie Chart Creator

This Pie Chart Maker converts raw data to percentages to create a circular statistical graph divided into proportional slices or sectors. The arc length of each slice is proportional to the quantity it represents.

Pie chart sectors are unsorted by default, with an option to order them clockwise by size.

The colours for sector categories are maintained in the ordering process, a useful feature when comparing pie chart data from different sites or times.

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

This Pie Chart Maker is free to use and no account or log-in is required.
