2 mins read

This article explains how to create a pie chart example in C# WPF in a step-by-step process.

The User Guide Documentation helps you to acquire more knowledge on chart and its features. You can also refer to the Feature Tour site to get an overview on all the features in chart. The assembly required for creating the chart is manifested in this documentation.

Step 1:

Create a DataModel for the PieSeries.

public class Person
{
    public string Name { get; set; }
    public double Weight { get; set; }
}

Step 2:

Create a ViewModel class with the DataModel collection to initialize datapoints for series.

public class ViewModel
{
    public List<Person> Data { get; set; }
 
    public ViewModel()
    {
        Data = new List<Person>()
        {
            new Person { Name = "David", Weight = 45 },
            new Person { Name = "Michael", Weight = 50 },
            new Person { Name = "Steve", Weight = 79 },
            new Person { Name = "Joel", Weight = 65 },
            new Person { Name = "Sam", Weight = 54 },
            new Person { Name = "Smith", Weight = 60 }
        };
    }
}

Step 3:

Initialize the chart with title by using the Header property of the chart and set the DataContext for the chart as ViewModel.

SfChart chart = new SfChart();
chart.DataContext = new ViewModel();
chart.Header = "Weight Report";
chart.Legend = new ChartLegend();

Step 4:

Define the PieSeries and add it to the chart.

PieSeries series = new PieSeries();
series.XBindingPath = "Name";
series.YBindingPath = "Weight";
series.ItemsSource = viewModel.Data;
chart.Series.Add(series);

The following code snippet gives you the consolidated configuration of all of the above codes.

SfChart chart = new SfChart();            
ViewModel viewModel = new ViewModel();
chart.DataContext = viewModel;
chart.Header = "Weight Report";
chart.Legend = new ChartLegend();
 
// Defining the PieSeries with adornments.
PieSeries series = new PieSeries();
series.XBindingPath = "Name";
series.YBindingPath = "Weight";
series.ItemsSource = viewModel.Data;
series.AdornmentsInfo = new ChartAdornmentInfo() 
{
    ShowLabel = true 
};
chart.Series.Add(series);
