This sample directs the visualization of moving wind types based on their speed via the legend of the circular gauge component. The visibility, shape, alignment, and position of the legend can all be customized.
The legend provides useful information for interpreting what the circular gauge's axis range displays, and it can be represented in a variety of colors, shapes, and other identifiers depending on the data. To do so, use the legendSettings and its properties.
More information on the legend can be found in this documentation section.
