Donut Chart Widgets

Use the Donut Chart widget to display a donut chart. Each slice in a donut chart corresponds to a field in the data received over the associated data channel.

The Data Field and the Chart Colors properties refer to the donut slices using a numbering scheme. Slice number 1 is the top right slice with numbering continuing clockwise:

The Start Angle and Donut Size properties determine the orientation and size of the donut. A default donut chart has a start angle of 0 (zero) and a size of 360 degrees. To create a partial donut, set the start angle to the angle at which you want the first slice to appear and specify the size of the donut, also in degrees.

For example, to create the following gauge-like semicircle donut, set the start angle to 270 and the donut size to 180. The first slice starts at 270 degrees with the data sources organized clockwise.
