# isFlipped

A Boolean that indicates if the ruler view’s coordinate system is flipped.

```
var isFlipped: Bool { get }
```

## Discussion

<doc://com.apple.documentation/documentation/Swift/true> if the receiver’s coordinate system is flipped, <doc://com.apple.documentation/documentation/Swift/false> otherwise.

A vertical ruler takes into account whether the coordinate system of the [`NSScrollView`](/documentation/AppKit/NSScrollView)‘s document view—not the receiver’s client view—is flipped. A horizontal ruler is always flipped.
