# init(xStart:xEnd:yStart:yEnd:)

Creates a bar mark that plots values with its x interval and fixed y position.

## Declaration

```swift
nonisolated init<X>(xStart: PlottableValue<X>, xEnd: PlottableValue<X>, yStart: CGFloat? = nil, yEnd: CGFloat? = nil) where X : Plottable
```

## Parameters

- `xStart`: The value plotted with x start.
- `xEnd`: The value plotted with x end.

## Discussion

Discussion Use this initializer to show horizontal intervals for one category: Chart(data) {    BarMark(        xStart: .value("Start Time", $0.start),        xEnd: .value("End Time", $0.end)    ) }
