# RulePlot Chart content that represents a collection of data using a single horizontal or vertical rule. ``` struct RulePlot ``` ## Overview Use `RulePlot` when you want to visualize data in the same way as with [`RuleMark`](/documentation/Charts/RuleMark), but you want to visualize an entire data collection with a single plot. You can initialize and style the plot with simple values or key paths. Add modifiers with `KeyPath` before adding modifiers with simple values. ``` Chart { RulePlot( tasks, xStart: .value("Start time", \.startTime), xEnd: .value("End time", \.endTime), y: .value("Project", \.project) ) .foregroundStyle(by: .value("Status", \.status)) .opacity(\.opacity) .lineStyle(StrokeStyle(lineWidth: 8, lineCap: .round)) } ``` ## Topics ### Plotting rules from a collection [`init(_:x:yStart:yEnd:)`](/documentation/Charts/RulePlot/init(_:x:yStart:yEnd:)-13wts) [`init(_:x:yStart:yEnd:)`](/documentation/Charts/RulePlot/init(_:x:yStart:yEnd:)-3fig9) [`init(_:x:yStart:yEnd:)`](/documentation/Charts/RulePlot/init(_:x:yStart:yEnd:)-6ts7e) [`init(_:x:yStart:yEnd:)`](/documentation/Charts/RulePlot/init(_:x:yStart:yEnd:)-8b2lx) [`init(_:x:yStart:yEnd:)`](/documentation/Charts/RulePlot/init(_:x:yStart:yEnd:)-zxo0) [`init(_:xStart:xEnd:y:)`](/documentation/Charts/RulePlot/init(_:xStart:xEnd:y:)-3dsvn) [`init(_:xStart:xEnd:y:)`](/documentation/Charts/RulePlot/init(_:xStart:xEnd:y:)-4yxo8) [`init(_:xStart:xEnd:y:)`](/documentation/Charts/RulePlot/init(_:xStart:xEnd:y:)-54gxx) [`init(_:xStart:xEnd:y:)`](/documentation/Charts/RulePlot/init(_:xStart:xEnd:y:)-8ehr7) [`init(_:xStart:xEnd:y:)`](/documentation/Charts/RulePlot/init(_:xStart:xEnd:y:)-hx5a) ### Supporting types [`body`](/documentation/Charts/ChartContent/body-swift.property) The content and behavior of the chart content.
