# strokeStart

The unit distance along the circle where the stroke starts.

```
var strokeStart: CGFloat { get set }
```

## Discussion

Use this property and [`strokeEnd`](/documentation/MapKit/MKCircleRenderer/strokeEnd) to render a portion of the line. As a unit distance, [`strokeStart`](/documentation/MapKit/MKCircleRenderer/strokeStart) must be a value between 0 and 1. A unit distance of 0 represents the top of the circle and the stroke draws in a clockwise direction.
