Introducing the New .NET MAUI Polar Charts Control

We are glad to introduce the new .NET MAUI Polar Charts control in our Essential Studio® 2024 Volume 1 release.  

The .NET MAUI Polar Charts control enhances visualization by elegantly representing data in terms of values and angles, making it an essential component for crafting visually appealing and informative .NET MAUI applications.

Polar charts help visualize cyclical data patterns, such as seasonal trends, periodic fluctuations, and directional relationships.

Let’s explore the features of the .NET MAUI Polar Charts control!

Key features

The key features of the .NET MAUI Polar Charts control include:

• Chart types
• Tooltips
• Data labels
• Legends

Chart types

Polar Area Chart

The Polar Area Chart helps us to show data in a circular pattern, compare values, and provide a clear and engaging way to present complex information.

Polar Line Chart

Each data point is represented as a particular location along a radial line in a Polar Line Chart.

Radar Area Chart

The Radar Area Chart displays data points that are visualized as areas within a polygon gridline.

Radar Line Chart

The Radar Line Chart displays data points that are visualized as a line in a polygon gridline.

Tooltips

Enhance user interaction and data exploration with tooltips that provide additional information about individual segments on the chart. Users can gain insights by hovering over data points and accessing relevant details.

Data labels

Enhance readability and comprehension by adding data labels to your Polar Chart. Label the data points to provide context and significance.

Legends

Use the legends to provide a quick reference guide to understand the chart’s content briefly. Legends offer a visual representation of data series, making it easier for users to interpret the chart.

Note: For more details, refer to the .NET MAUI Polar Charts control documentation.

Getting started with the .NET MAUI Polar Charts control

We’ve explored the features of the .NET MAUI Polar Charts control. Let’s see the steps to integrate it into your .NET MAUI app.

Step 1: Create a .NET MAUI app

First, create a .NET MAUI application.

Step 2: Add the required NuGet package

Syncfusion .NET MAUI controls are available on the NuGet Gallery. To add the .NET MAUI Polar Charts control to your project, open the NuGet package manager in Visual Studio. Search for Syncfusion.Maui.Charts and then install it.

Step 3: Register the handler

Now, register the handler for the Syncfusion core in the MauiProgram.cs file.

using Microsoft.Maui;
using Microsoft.Maui.Hosting;
using Microsoft.Maui.Controls.Compatibility;
using Microsoft.Maui.Controls.Hosting;
using Microsoft.Maui.Controls.Xaml;
using Syncfusion.Maui.Core.Hosting;

namespace SunburstGettingStarted
{
    public static class MauiProgram
    {
        public static MauiApp CreateMauiApp()
        {
            var builder = MauiApp.CreateBuilder();
            builder
              .UseMauiApp<App>()
              .ConfigureSyncfusionCore()
              .ConfigureFonts(fonts =>
              {
                 fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
              });

              return builder.Build();
        }
    }
}

Step 4: Add the namespace

Add the Syncfusion.Maui.Charts namespace in your XAML page.

<ContentPage   
  . . .
  xmlns:chart=" clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts">
  . . .
</ContentPage>

Step 5: Initialize the Syncfusion .NET MAUI Polar Charts control

Finally, initialize the .NET MAUI Polar Charts control with the data, as shown in the following code example.

<ContentPage
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="ChartGettingStarted.MainPage"
    xmlns:chart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts"
    xmlns:model="clr-namespace:ChartGettingStarted">

 <!--Create business objects and specify binding context-->

 <ContentPage.BindingContext>
  <model:ViewModel></model:ViewModel>
 </ContentPage.BindingContext>

 <ContentPage.Content>
  <Grid>
   <chart:SfPolarChart>
    <chart:SfPolarChart.Title>
     <Label Text="Plant Analysis"/>
    </chart:SfPolarChart.Title>

    <chart:SfPolarChart.Legend>
     <chart:ChartLegend/>
    </chart:SfPolarChart.Legend>
    
    <chart:SfPolarChart.PrimaryAxis>
     <chart:CategoryAxis/>                    
    </chart:SfPolarChart.PrimaryAxis>

    <chart:SfPolarChart.SecondaryAxis>
     <chart:NumericalAxis/>                   
    </chart:SfPolarChart.SecondaryAxis>

    <chart:PolarAreaSeries Label="Tree" 
                           EnableTooltip="True"
                           ShowDataLabels="True"
                           ItemsSource="{Binding PlantDetails}"
                           XBindingPath="Direction" YBindingPath="Tree">
     <chart:PolarAreaSeries.DataLabelSettings>
      <chart:PolarDataLabelSettings LabelPlacement="Auto"/>
     </chart:PolarAreaSeries.DataLabelSettings>
    </chart:PolarAreaSeries>
   </chart:SfPolarChart>
  </Grid>
 </ContentPage.Content>
</ContentPage>

After executing the above code examples, we will get the output that resembles the following image.
