The Stacked Mountain Series Type

The Stacked Mountain series can be created by using SCIStackedMountainRenderableSeries and SCIVerticallyStackedMountainsCollection classes. Stacked Mountain series shares most of its properties with the regular Mountain (Area) Series, with the added feature that mountains are automatically stacked (aggregate its Y-Values).

NOTE: In multi axis scenarios, a series has to be assigned to particular X and Y axes. This can be done by passing the axes IDs to the ISCIRenderableSeries.xAxisId, ISCIRenderableSeries.yAxisId properties.

Stacked Mountain Series Type

NOTE: Examples of the Stacked Mountain Series can be found in the SciChart iOS Examples Suite as well as on GitHub:

How the Stacking Works for Mountain Series

Stacking Mountain series is handled by special renderableSeries - SCIVerticallyStackedMountainsCollection.

Basically, it’s a simple SCIObservableCollection of Stacked Mountain Series, where the order of items in it determines how series should be stacked and drawn - the first item will be drawn as regular mountain series and the rest will be stacked on top of each other.

If you want to have several sets of Stacked Mountain Series which should be stacked independently, all you need to do - is to create corresponding amount of SCIVerticallyStackedMountainsCollection which will hold appropriate SCIStackedMountainRenderableSeries.

Create a Vertically Stacked Mountain Series

To create a Vertically Stacked Mountain Series, use the following code:

// Assume a surface has been created and configured somewhere id<ISCIChartSurface> surface; // Create DataSeries and fill it with some data SCIXyDataSeries *ds1 = [[SCIXyDataSeries alloc] initWithXType:SCIDataType_Double yType:SCIDataType_Double]; SCIXyDataSeries *ds2 = [[SCIXyDataSeries alloc] initWithXType:SCIDataType_Double yType:SCIDataType_Double]; // Create Stacked Mountain Series SCIStackedMountainRenderableSeries *rSeries1 = [SCIStackedMountainRenderableSeries new]; rSeries1.dataSeries = ds1; rSeries1.strokeStyle = [[SCISolidPenStyle alloc] initWithColorCode:0xFFffffff thickness:1.0]; rSeries1.areaStyle = [[SCILinearGradientBrushStyle alloc] initWithStart:CGPointZero end:CGPointMake(0.0, 1.0) startColorCode:0xDDDBE0E1 endColorCode:0x88B6C1C3]; SCIStackedMountainRenderableSeries *rSeries2 = [SCIStackedMountainRenderableSeries new]; rSeries2.dataSeries = ds2; rSeries2.strokeStyle = [[SCISolidPenStyle alloc] initWithColorCode:0xFFffffff thickness:1.0]; rSeries2.areaStyle = [[SCILinearGradientBrushStyle alloc] initWithStart:CGPointZero end:CGPointMake(0.0, 1.0) startColorCode:0xDDACBCCA endColorCode:0x88439AAF]; // Create and Fill Stacked Series Collection SCIVerticallyStackedMountainsCollection *seriesCollection = [SCIVerticallyStackedMountainsCollection new]; [seriesCollection add:rSeries1]; [seriesCollection add:rSeries2]; [surface.renderableSeries add:seriesCollection];
// Assume a surface has been created and configured somewhere let surface: ISCIChartSurface // Create DataSeries and fill it with some data let ds1 = SCIXyDataSeries(xType: .double, yType: .double) let ds2 = SCIXyDataSeries(xType: .double, yType: .double) // Create Stacked Mountain Series let rSeries1 = SCIStackedMountainRenderableSeries() rSeries1.dataSeries = ds1 rSeries1.strokeStyle = SCISolidPenStyle(colorCode: 0xFFffffff, thickness: 1) rSeries1.areaStyle = SCILinearGradientBrushStyle(start: CGPoint(x: 0.0, y: 0.0), end: CGPoint(x: 1.0, y: 1.0), startColorCode: 0xDDDBE0E1, endColorCode: 0x88B6C1C3) let rSeries2 = SCIStackedMountainRenderableSeries() rSeries2.dataSeries = ds2 rSeries2.strokeStyle = SCISolidPenStyle(colorCode: 0xFFffffff, thickness: 1) rSeries2.areaStyle = SCILinearGradientBrushStyle(start: CGPoint(x: 0.0, y: 0.0), end: CGPoint(x: 1.0, y: 1.0), startColorCode: 0xDDACBCCA, endColorCode: 0x88439AAF) // Create and Fill Stacked Series Collection let seriesCollection = SCIVerticallyStackedMountainsCollection() seriesCollection.add(rSeries1) seriesCollection.add(rSeries2) surface.renderableSeries.add(seriesCollection)
// Assume a surface has been created and configured somewhere IISCIChartSurface surface; // Create DataSeries and fill it with some data var ds1 = new XyDataSeries<double, double> { SeriesName = “data 1” }; var ds2 = new XyDataSeries<double, double> { SeriesName = “data 2” }; // Create Stacked Mountain Series var rSeries1 = new SCIStackedMountainRenderableSeries { DataSeries = ds1, StrokeStyle = SCISolidPenStyle(colorCode: 0xFFffffff, thickness: 1), AreaStyle = new SCILinearGradientBrushStyle(new CGPoint(0, 0), new CGPoint(1, 1), 0xDDDBE0E1, 0x88B6C1C3) }; var rSeries2 = new SCIStackedMountainRenderableSeries { DataSeries = ds2, StrokeStyle = SCISolidPenStyle(colorCode: 0xFFffffff, thickness: 1), AreaStyle = new SCILinearGradientBrushStyle(new CGPoint(0, 0), new CGPoint(1, 1), 0xDDACBCCA, 0x88439AAF) }; // Create and Fill Stacked Series Collection var seriesCollection = new SCIVerticallyStackedMountainsCollection(); seriesCollection.Add(rSeries1); seriesCollection.Add(rSeries2); surface.RenderableSeries.Add(seriesCollection);

100% Stacked Mountains

Similarly to Stacked Column Series in SciChart it is possible to have Stacked Mountains, which fills all available vertical space. This mode is called 100% Stacked Mountains.

To use it on your SCIVerticallyStackedMountainsCollection, just change the corresponding property of your collection:
