By the end of this guide, you’ll have built a fully functional, customized wind direction visualization dashboard that you can adapt for your projects.

Let’s dive in!

What is a Radar Chart?

A Radar Chart, also called a spider or web chart, is a graphical tool for displaying multivariate data, where a set of variables is represented on axes originating from a central point.

This chart type is especially effective for illustrating relative strengths and identifying patterns, making it a great choice for visualizing wind direction. When applied to wind direction, the radar chart showcases various angles ( typically in degrees ) that represent wind directions, with the chart filled to depict wind intensity at each angle.

Setting up the Radar Chart in Syncfusion® React Charts

The following steps will guide you in creating a radar chart using Syncfusion’s React components and efficiently rendering data to gain valuable insights:

Step 1: Installing and importing required packages

First, install the necessary Syncfusion® packages:

npm install @syncfusion/ej2-react-charts
Enter fullscreen mode Exit fullscreen mode

Then, import the required components in your React file:

import React from 'react'; import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, AreaSeries, RadarSeries, Highlight } from '@syncfusion/ej2-react-charts';
Enter fullscreen mode Exit fullscreen mode

Step 2: Gathering the wind direction data

Before visualizing data in React Charts, it is essential to gather accurate and meaningful statistics. In this example, the wind direction data for four cities: Miami, Austin, New York, and Chicago are sourced from various sources.

Step 3: Preparing data for the chart

For a React-based radar chart, the data should be structured as an array of JSON objects, where each JSON object represents a single data point. Each object should include fields for the X-axis (e.g., direction) and the Y-axis (e.g., percentage).

export const miami = [ { direction: 'North', percentage: 8 }, { direction: 'NorthEast', percentage: 13 }, { direction: 'East', percentage: 33 }, { direction: 'SouthEast', percentage: 19 }, { direction: 'South', percentage: 9 }, { direction: 'SouthWest', percentage: 9 }, { direction: 'West', percentage: 5 }, { direction: 'NorthWest', percentage: 8 }, ];
Enter fullscreen mode Exit fullscreen mode

Step 4: Initializing the Syncfusion® React Radar Chart

To create an impressive visualization of wind direction, you can leverage the Syncfusion® React Charts component and configure it effectively to suit your needs. Syncfusion® provides extensive tools and customization options to enhance your charts’ interactivity and aesthetics. If you need additional guidance, Syncfusion’s comprehensive documentation is a great resource to explore.

Here’s a complete example for setting up a radar chart to visualize wind direction:

<ChartComponent> <Inject services={[AreaSeries, Legend, Tooltip, Category, RadarSeries, Highlight]} /> <SeriesCollectionDirective> <SeriesDirective></SeriesDirective> </SeriesCollectionDirective> </ChartComponent>
Enter fullscreen mode Exit fullscreen mode

Step 5: Binding wind direction data to Syncfusion® React Charts

The SeriesDirective component seamlessly integrates wind direction data into the Syncfusion® React Chart. This component allows you to bind a data source, configure the X and Y values, and customize the appearance of the radar chart for effective visualization.

Since the data is displayed in a radar chart, the type property must be set to Radar, and drawType property must be set to Area. This configuration fills the area under the radar series, providing a visually distinct representation of the data.

Here’s an example of how you can achieve this for a single city:

<SeriesDirective dataSource={miami} xName='direction' yName='percentage' type="Radar" drawType='Area'> </SeriesDirective>
Enter fullscreen mode Exit fullscreen mode

In this example, the miami array, which contains the direction data, is bound to the dataSource property of the chart. The direction field is mapped to the xName property, and the percentage field is mapped to the yName property. This configuration ensures that each data point is accurately represented on the chart, clearly representing the wind direction in Miami.

Step 6: Customizing the appearance of Radar Charts

To enhance the visual appeal of the radar chart in Syncfusion® React, you can customize various elements. This includes adding a title and subtitle to provide context, displaying axis labels for clarity, and adjusting the area style to improve the overall look and readability of the chart.

Here’s how you can add and customize the title and subtitle of the chart:

<ChartComponent title='Wind Direction Trends Across Major US Cities in 2024' subTitle="Yearly Wind Direction Analysis for Major US Cities in 2024"> </ChartComponent>
Enter fullscreen mode Exit fullscreen mode

Customizing the series

You can customize the appearance of the series in Syncfusion® React charts by modifying the fill, opacity, and border properties. The fill property allows you to set the interior color of the series, while the opacity property controls its transparency, with values ranging from 0 (fully transparent) to 1 (fully opaque).

Additionally, you can customize the series border using the width property to define the border thickness and the color property to specify the border color. These properties help enhance the visual aesthetics and clarity of the chart.

Refer to the following code to customize the series:

<SeriesDirective fill="#008080" border={{ width: 2 }} type="Radar" drawType='Area' opacity="0.5"> </SeriesDirective>
Enter fullscreen mode Exit fullscreen mode

Customizing the axis labels

We can control the visibility of gridlines and tick lines by using the majorGridLines and majorTickLines properties in the primaryXAxis and primaryYAxis.

Additionally, to change the format of the labels on the Y-axis, you can use the labelFormat property in the primaryYAxis.

Here’s an example code for reference:

primaryXAxis={{ labelPlacement: 'OnTicks', labelStyle: { color: 'black' } }} primaryYAxis={{ labelFormat: '{value}%' }}
Enter fullscreen mode Exit fullscreen mode

Adding the legend

To add a legend in Syncfusion® React Charts, you can enable the legend by setting the visible property to true within the legendSettings object. You can also control the position of the legend using the position property in legendSettings, allowing you to place the legend at different locations (such as top, bottom, left, or right).

Additionally, you need to inject the Legend module into the chart’s services to render the legend.

legendSettings={{ visible: true, position: 'Right', title: 'Cities' }}
Enter fullscreen mode Exit fullscreen mode

Changing the legend shape

You can customize the shape of the legend for each series in Syncfusion® React Charts by using the legendShape property within the individual series configuration. This property allows you to specify the shape of the legend, such as a circle, rectangle, or even an image, depending on your preference.

Here’s an example of how to modify the legend shape for a series:

<SeriesDirective legendShape="Triangle"> </SeriesDirective>
Enter fullscreen mode Exit fullscreen mode

After running the above code examples, the output will appear as shown in the following image:
