Stacked Line Chart

The Ignite UI for Angular stacked line chart belongs to a group of category charts and is rendered using a collection of points connected by line segments (IgxStackedFragmentSeriesComponent) that are stacked on top of each other. Each stacked fragment in the collection represents one visual element in each stack. Each stack can contain both positive and negative values. All positive values are grouped on the positive side of the y-axis, and all negative values are grouped on the negative side of the y-axis.

Demo

The IgxStackedLineSeriesComponent has its own IgxSeriesComponent collection in which you can place the IgxStackedFragmentSeriesComponent elements. These fragments are what make up the actual rendering of the chart and are the elements that accept the valueMemberPath.

Required Axes

The Angular data chart component provides various types of axes but only the following types of axes can be used with IgxStackedLineSeriesComponent.

Required Data

The IgxStackedLineSeriesComponent has the following data requirements:

Required Modules

Creation of the IgxStackedLineSeriesComponent requires the following modules:

// axis' modules:
import { IgxCategoryXAxis } from 'igniteui-angular-charts';
import { IgxNumericYAxis } from 'igniteui-angular-charts';
// series' modules:
import { IgxStackedLineSeries } from 'igniteui-angular-charts';
// data chart's modules:

import { IgxDataChartCoreModule } from 'igniteui-angular-charts';
import { IgxDataChartCategoryModule } from 'igniteui-angular-charts';
import { IgxDataChartStackedModule } from 'igniteui-angular-charts';

@NgModule({
    imports: [
        // ...
        IgxDataChartCoreModule,
        IgxDataChartCategoryModule,
        IgxDataChartStackedModule
        // ...
    ]
})

Code Example

This code demonstrates how to create an instance of the Ignite UI for Angular data chart with IgxStackedLineSeriesComponent and bind it to a data source.

<igx-data-chart #chart height="100%" width="100%" [dataSource]="data">
  <igx-category-x-axis #xAxis label="Country"></igx-category-x-axis>
  <igx-numeric-y-axis #yAxis></igx-numeric-y-axis>

  <igx-stacked-line-series [xAxis]="xAxis" [yAxis]="yAxis">
    <igx-stacked-fragment-series valueMemberPath="Coal"></igx-stacked-fragment-series>
    <igx-stacked-fragment-series valueMemberPath="Hydro"></igx-stacked-fragment-series>
    <igx-stacked-fragment-series valueMemberPath="Nuclear"></igx-stacked-fragment-series>
    <igx-stacked-fragment-series valueMemberPath="Gas"></igx-stacked-fragment-series>
    <igx-stacked-fragment-series valueMemberPath="Oil"></igx-stacked-fragment-series>
  </igx-stacked-line-series>

</igx-data-chart>
