# init(x:yStart:yEnd:width:)

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

## Declaration

```swift
nonisolated init<X, Y>(x: PlottableValue<X>, yStart: PlottableValue<Y>, yEnd: PlottableValue<Y>, width: MarkDimension = .automatic) where X : Plottable, Y : Plottable
```

## Parameters

- `x`: The value plotted with x.
- `yStart`: The value plotted with y start.
- `yEnd`: The value plotted with y end.
- `width`: The bar width. If width is nil, the default bar size will be applied.

## Discussion

Discussion Use this initializer to show vertical intervals for one or more categories: Chart(data) {    BarMark(        x: .value("Job", $0.job),        yStart: .value("Start Time", $0.start),        yEnd: .value("End Time", $0.end)    ) }
