## Declaration

```swift
func drawHashMarksAndLabels(in rect: NSRect)
```

## Discussion

Discussion This method is invoked by draw(_:)—you should never need to invoke it directly. You can define custom measurement units using the class method registerUnit(withName:abbreviation:unitToPointsConversionFactor:stepUpCycle:stepDownCycle:). Override this method if you want to customize the appearance of the hash marks themselves.
