Radial Column Chart

The Ignite UI for Angular radial column chart belongs to a group of radial charts and is rendered using a collection of rectangles that extend from the center of the chart towards the locations of data points. The IgxRadialColumnSeriesComponent uses the same concepts of data plotting as the IgxColumnSeriesComponent but wraps data points around a circle rather than stretching them along a horizontal line.

Demo

Required Axes

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

Required Data

The IgxRadialColumnSeriesComponent 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 IgxRadialColumnSeriesComponent.
  • All data items must contain at least one label data column (string or date time) which should be mapped to the Label property of the category axis (e.g. IgxCategoryAngleAxisComponent).
  • All data items must contain at least one numeric data column which should be mapped using the valueMemberPath property of the IgxRadialColumnSeriesComponent.

You can use the SampleRadialData as data source which meets above data requirements.

this.chart.dataSource = SampleRadialData.create();

Required Modules

Creation of the IgxRadialColumnSeriesComponent requires the following modules:

// axis' modules:
import { IgxCategoryAngleAxis } from "igniteui-angular-charts/ES5/igx-category-angle-axis";
import { IgxNumericRadiusAxis } from "igniteui-angular-charts/ES5/igx-numeric-radius-axis";
// series modules:
import { IgxRadialColumnSeries } from "igniteui-angular-charts/ES5/igx-radial-column-series";
// data chart's modules:

import { IgxDataChartCoreModule } from "igniteui-angular-charts/ES5/igx-data-chart-core-module";
import { IgxDataChartRadialCoreModule } from "igniteui-angular-charts/ES5/igx-data-chart-radial-core-module";
import { IgxDataChartRadialModule } from "igniteui-angular-charts/ES5/igx-data-chart-radial-module";

@NgModule({
    imports: [
        // ...
        IgxDataChartCoreModule,
        IgxDataChartRadialCoreModule,
        IgxDataChartRadialModule,
        // ...
    ]
})

Code Example

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

 <igx-data-chart
    [dataSource]="dataSource"
    width="700px"
    height="500px">
    <igx-category-angle-axis name="angleAxis" label="Department"></igx-category-angle-axis>
    <igx-numeric-radius-axis name="radiusAxis"></igx-numeric-radius-axis>
    <igx-radial-column-series
        name="series1"
        valueMemberPath="Budget"
        valueAxisName="radiusAxis"
        angleAxisName="angleAxis">
    </igx-radial-column-series>
 </igx-data-chart>
