Stacked 100 Area Chart

The Ignite UI for Angular stacked 100 area chart belongs to a group of category charts and is rendered using a collection of points connected by line segments (IgxStackedFragmentSeriesComponent) with the area below the line filled in and 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. The Angular stacked 100 area chart is identical to the Angular stacked area chart in all aspects except in their treatment of the values on y-axis. Instead of presenting a direct representation of the data, the IgxStacked100AreaSeriesComponent presents the data in terms of percent of the sum of all values in a data point.

Demo

The IgxStacked100AreaSeriesComponent 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 IgxStacked100AreaSeriesComponent.

Required Data

The IgxStacked100AreaSeriesComponent has the following data requirements:

Required Modules

Creation of the IgxStacked100AreaSeriesComponent requires the following modules:

// axis' modules:
import { IgxCategoryXAxis } from 'igniteui-angular-charts';
import { IgxNumericYAxis } from 'igniteui-angular-charts';
// series' modules:
import { IgxStacked100AreaSeries } 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 IgxStacked100AreaSeriesComponent 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-100-area-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-100-area-series>

</igx-data-chart>
