# translateX(by:yBy:)

Applies the specified translation factors to the receiver’s transformation matrix.

## Declaration

```swift
func translateX(by deltaX: Double, yBy deltaY: Double)
```

## Parameters

- `deltaX`: The number of units to move along the x axis.
- `deltaY`: The number of units to move along the y axis.

## Discussion

Discussion Subsequent transformations cause coordinates to be shifted by deltaX units along the x axis and by deltaY units along the y axis. Translation factors do not affect NSSize values, which specify a differential between points.
