Stacked 100 Line Chart

The Ignite UI for Web Components stacked 100 line chart belongs to a group of category charts and is rendered using a collection of points connected by line segments (IgcStackedFragmentSeriesComponent) 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. The Web Components stacked 100 line chart is identical to the Web Components stacked line chart in all aspects except in their treatment of the values on y-axis. Instead of presenting a direct representation of the data, the IgcStacked100LineSeriesComponent presents the data in terms of percent of the sum of all values in a data point.

Demo

The IgcStacked100LineSeriesComponent has its own IgcSeriesComponent collection in which you can place the IgcStackedFragmentSeriesComponent elements. These fragments are what make up the actual rendering of the chart and are the elements that accept the valueMemberPath.

Required Axes

The Web Components data chart component provides various types of axes but only the following types of axes can be used with IgcStacked100LineSeriesComponent.

• IgcCategoryXAxisComponent
• IgcOrdinalTimeXAxisComponent
• IgcTimeXAxisComponent
• IgcNumericYAxisComponent

Required Data

The IgcStacked100LineSeriesComponent has the following data requirements:

• The data source must be an array or a list of data items.
• The data source must contain at least one data item otherwise the chart will not render the IgcStacked100LineSeriesComponent.
• All data items must contain at least one data column (string or date time) which should be mapped to the Label property of the category axis (e.g. IgcCategoryXAxisComponent).
• All data items must contain at least one numeric data column which should be mapped using the ValueMemberPath property of the IgcStackedFragmentSeriesComponent to be added to the IgcStacked100LineSeriesComponent' IgcSeriesComponent collection.

Required Modules

Creation of the IgcStacked100LineSeriesComponent requires the following modules:

import { IgcDataChartComponent } from 'igniteui-webcomponents-charts';
import { IgcDataChartCoreModule } from 'igniteui-webcomponents-charts';
import { IgcDataChartCategoryModule } from 'igniteui-webcomponents-charts';
import { IgcDataChartStackedModule } from 'igniteui-webcomponents-charts';
import { IgcStackedFragmentSeriesModule } from 'igniteui-webcomponents-charts';
import { ModuleManager } from 'igniteui-webcomponents-core';

ModuleManager.register(
    IgcDataChartCoreModule,
    IgcDataChartCategoryModule,
    IgcDataChartStackedModule,
    IgcStackedFragmentSeriesModule,
);

Code Example
