Getting Started

This article will guide you through the steps needed to add a basic RadChart control in your application.

1. Setting up the app

Take a look at these articles and follow the instructions to set up your app:

2. Adding the required Telerik references

You have two options:

  • Add the Telerik UI for Xamarin Nuget packages following the instructions in Telerik NuGet package server topic.

  • Add the references to Telerik assemblies manually, check the list below with the required assemblies for RadChart component:

Platform Assemblies
Portable Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Chart.dll
Android Telerik.Xamarin.Android.Common.dll
Telerik.Xamarin.Android.Chart.dll
Telerik.Xamarin.Android.Primitives.dll
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Chart.dll
iOS Telerik.Xamarin.iOS.dll
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Chart.dll
UWP Telerik.Core.dll
Telerik.UI.Xaml.Chart.UWP.dll
Telerik.UI.Xaml.Primitives.UWP.dll
Telerik.XamarinForms.Common.dll
Telerik.XamarinForms.Chart.dll

3. Adding RadChart control

You could use one of the following approaches:

Drag the control from the Toolbox.

Take a look at the following topics on how to use the toolbox:

Create the control definition in XAML or C#.

The snippet below shows a simple RadChart definition:

<telerikChart:RadCartesianChart x:Name="chart">
  <telerikChart:RadCartesianChart.BindingContext>
    <local:ViewModel />
  </telerikChart:RadCartesianChart.BindingContext>
  <telerikChart:RadCartesianChart.HorizontalAxis>
    <telerikChart:CategoricalAxis />
  </telerikChart:RadCartesianChart.HorizontalAxis>
  <telerikChart:RadCartesianChart.VerticalAxis>
    <telerikChart:NumericalAxis />
  </telerikChart:RadCartesianChart.VerticalAxis>
  <telerikChart:RadCartesianChart.Series>
    <telerikChart:BarSeries CategoryBinding="Category" 
                            ValueBinding="Value" 
                            ItemsSource="{Binding Data}" />
  </telerikChart:RadCartesianChart.Series>
</telerikChart:RadCartesianChart>
var chart = new RadCartesianChart
{
    HorizontalAxis = new CategoricalAxis(),
    VerticalAxis = new NumericalAxis(),
    BindingContext = new ViewModel()
};

var series = new BarSeries();

series.SetBinding(ChartSeries.ItemsSourceProperty, new Binding("Data"));

series.ValueBinding = new PropertyNameDataPointBinding { PropertyName = "Value" };
series.CategoryBinding = new PropertyNameDataPointBinding { PropertyName = "Category" };

chart.Series.Add(series);

In addition to this, you need to add the following namespace:

xmlns:telerikChart="clr-namespace:Telerik.XamarinForms.Chart;assembly=Telerik.XamarinForms.Chart"
using Telerik.XamarinForms.Chart;

4. Populating RadChart with data

Here is how the business model is defined:

public class CategoricalData
{
    public object Category { get; set; }

    public double Value { get; set; }
}

Here is the sample data used as binding context:

public class ViewModel
{
    public ViewModel()
    {
        this.Data = GetCategoricalData();
    }

    public ObservableCollection<CategoricalData> Data { get; set; }

    private static ObservableCollection<CategoricalData> GetCategoricalData()
    {
        var data = new ObservableCollection<CategoricalData>  {
            new CategoricalData { Category = "A", Value = 0.63 },
            new CategoricalData { Category = "B", Value = 0.85 },
            new CategoricalData { Category = "C", Value = 1.05 },
            new CategoricalData { Category = "D", Value = 0.96 },
            new CategoricalData { Category = "E", Value = 0.78 },
        };

        return data;
    }
}

Here is the result:

Basic RadCartesianChart

SDK Browser and QSF applications contain different examples that show RadChart's main features. You can find the applications in the Examples and QSF folders of your local Telerik UI for Xamarin installation.
