Radial Area Chart

The Ignite UI for React radial area chart belongs to a group of radial charts and has a shape of a filled polygon that is bound by a collection of straight lines connecting data points. The IgrRadialAreaSeries uses the same concepts of data plotting as the IgrAreaSeries but wraps data points around a circle rather than stretching them along a horizontal line.

Demo

Required Axes

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

Required Data

The IgrRadialAreaSeries 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 IgrRadialAreaSeries.
  • 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. IgrCategoryAngleAxis).
  • All data items must contain at least one numeric data column which should be mapped using the valueMemberPath property of the IgrRadialAreaSeries.

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

public dataSource: any[] = SampleRadialData.create();

Required Modules

Creation of the IgrRadialAreaSeries requires the following modules:

// axis' modules:
import { IgrCategoryAngleAxis } from 'igniteui-react-charts';
import { IgrNumericRadiusAxis } from 'igniteui-react-charts';
// series modules:
import { IgrRadialAreaSeries } from 'igniteui-react-charts';
import { IgrRadialLineSeries } from 'igniteui-react-charts';
import { IgrRadialPieSeries } from 'igniteui-react-charts';
import { IgrRadialColumnSeries } from 'igniteui-react-charts';
// data chart's modules:
import { IgrDataChart } from 'igniteui-react-charts';
import { IgrDataChartCoreModule } from 'igniteui-react-charts';
import { IgrDataChartRadialCoreModule } from 'igniteui-react-charts';
import { IgrDataChartRadialModule } from 'igniteui-react-charts';

// registering data chart's modules:
IgrDataChartCoreModule.register();
IgrDataChartRadialCoreModule.register();
IgrDataChartRadialModule.register();

Code Example

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

<IgrDataChart
    dataSource={this.state.dataSource}
    width="700px"
    height="500px">
    <IgrCategoryAngleAxis name="angleAxis" label="Department" />
    <IgrNumericRadiusAxis name="radiusAxis" />
    <IgrRadialAreaSeries
        name="series1"
        valueMemberPath="Budget"
        valueAxisName="radiusAxis"
        angleAxisName="angleAxis" />
</IgrDataChart>

const series1 = new IgrRadialAreaSeries({ name: "series1" });
series1.valueMemberPath  = "Budget";
series1.radiusAxisName = "radiusAxis";
series1.angleAxisName = "angleAxis";

const radiusAxis = new IgrNumericRadiusAxis({ name: "radiusAxis" });
const angleAxis = new IgrCategoryAngleAxis({ name: "angleAxis" });
angleAxis.label = "Department";

this.chart = new IgrDataChart({ name: "chart" });
this.chart.dataSource = SampleCategoryData.create();
this.chart.axes.add(radiusAxis);
this.chart.axes.add(angleAxis);
this.chart.series.add(series1);
