The Stacked Mountain Series Type

Stacked Mountain Charts can be created by a combination of the StackedMountainRenderableSeries and StackedMountainCollection types. StackedMountainRenderableSeries share many properties with the added feature that columns automatically stack vertically or side by side.

The JavaScript Stacked Mountain Chart Example can be found in the SciChart.Js Examples Suite on Github, or our live demo at

Fast, Realtime JavaScript Stacked Mountain Charts by SciChart.js

Create a Stacked Mountain Series

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

Example Title
Copy Code
// Create a SciChartSurface
const { wasmContext, sciChartSurface } = await SciChartSurface.create(divElementId);
// Create an xAxis, yAxis
sciChartSurface.xAxes.add(new NumericAxis(wasmContext));
sciChartSurface.yAxes.add(new NumericAxis(wasmContext, {growBy: new NumberRange(0, 0.1)}));
// Create 3 DataSeries for our 3 stacked mountains
const dataSeries1 = new XyDataSeries(wasmContext, { xValues, yValues: y1Values });
const dataSeries2 = new XyDataSeries(wasmContext, { xValues, yValues: y2Values });
const dataSeries3 = new XyDataSeries(wasmContext, { xValues, yValues: y3Values });
// Create the three Stacked Mountain series
const rendSeries1 = new StackedMountainRenderableSeries(wasmContext);
rendSeries1.dataSeries = dataSeries1;
rendSeries1.fill = "#939899";
rendSeries1.rolloverModifierProps.markerColor = "#7b7e80";
rendSeries1.rolloverModifierProps.tooltipColor = "rgba(147,152,153,0.7)";
rendSeries1.rolloverModifierProps.tooltipTextColor = "#000";
const rendSeries2 = new StackedMountainRenderableSeries(wasmContext);
rendSeries2.dataSeries = dataSeries2;
rendSeries2.fill = "#66838d";
rendSeries2.rolloverModifierProps.markerColor = "#495d65";
rendSeries2.rolloverModifierProps.tooltipColor = "rgba(102,131,141,0.7)";
rendSeries2.rolloverModifierProps.tooltipTextColor = "#000";
const rendSeries3 = new StackedMountainRenderableSeries(wasmContext);
rendSeries3.dataSeries = dataSeries3;
rendSeries3.fill = "#368BC1";
rendSeries3.rolloverModifierProps.markerColor = "#2d739e";
rendSeries3.rolloverModifierProps.tooltipColor = "rgba(54,139,193,0.7)";
rendSeries3.rolloverModifierProps.tooltipTextColor = "#000";
// Group these StackedMountain series together in a StackedMountainCollection
const verticallyStackedMountainCollection = new StackedMountainCollection(wasmContext);
verticallyStackedMountainCollection.add(rendSeries1, rendSeries2, rendSeries3);
// Add the StackedMountainCollection to the chart



Creating 100% Stacked Mountain Charts

SciChart.js also supports a JavaScript 100% Stacked Mountain chart, which can be enabled by setting a single flag: StackedMountainCollection.isOneHundredPercent.

100% Stacked Mountain Series
Copy Code
const stackedMountainCollection = new StackedMountainCollection(wasmContext);
stackedMountainCollection.isOneHundredPercent = true;
stackedMountainCollection.add(rendSeries1, rendSeries2, rendSeries3);

 Setting this flag results in the following output.
