# init(x:y:z:)

Creates a rectangle mark for a 3D chart.

## Declaration

```swift
nonisolated init(x: PlottableValue<some Plottable>, y: PlottableValue<some Plottable>, z: PlottableValue<some Plottable>)
```

## Parameters

- `x`: The x value.
- `y`: The y value.
- `z`: The z value.

## Discussion

Discussion important: A 3D RectangleMark requires one parameter to be a single numeric value and the other two parameters to be numeric ranges. For example, the following Chart3D shows a rectangle mark that extends along the x-axis and y-axis. Chart3D {     RectangleMark(         x: .value("x", -0.5..<0.5),         y: .value("y", -0.5..<0.5),         z: .value("z", 0)     ) }
