# init(xStart:xEnd:y:height:stacking:)

Creates a bar mark that plots values on y with fixed x interval.

## Declaration

```swift
nonisolated init<Y>(xStart: CGFloat? = nil, xEnd: CGFloat? = nil, y: PlottableValue<Y>, height: MarkDimension = .automatic, stacking: MarkStackingMethod = .standard) where Y : Plottable
```

## Parameters

- `xStart`: The x start position. If xStart is nil then the rectangle will start at the leading edge of the plotting area.
- `xEnd`: The x end position. If xStart is nil then the rectangle will end at the trailing edge of the plotting area.
- `y`: The value plotted with y.
- `height`: The bar height. If height is nil, the default bar size will be applied.
- `stacking`: The stacking method for the bars with the same categorical/date values. If stacking is nil, the bars will not be stacked.

## Discussion

Discussion Use this initializer to create a chart with a single vertical bar: Chart(data) {     BarMark(         y: .value("Profit", $0.profit)     )     .foregroundStyle(by: .value("Product Category", $0.productCategory)) }
