Quick Start Example

Basic Pyramid Chart Implementation

XAML:

<Window
    x:Class="PyramidChartApp.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:chart="using:Syncfusion.UI.Xaml.Charts"
    xmlns:local="using:PyramidChartApp">
    
    <chart:SfPyramidChart x:Name="chart"
                          Header="Food Nutrition Pyramid"
                          ItemsSource="{Binding Data}"
                          XBindingPath="FoodName"
                          YBindingPath="Calories"
                          EnableTooltip="True"
                          ShowDataLabels="True">
        
        <chart:SfPyramidChart.DataContext>
            <local:ChartViewModel/>
        </chart:SfPyramidChart.DataContext>
        
        <chart:SfPyramidChart.Legend>
            <chart:ChartLegend/>
        </chart:SfPyramidChart.Legend>
        
    </chart:SfPyramidChart>
</Window>

View Model (C#):

public class Model
{
    public string FoodName { get; set; }
    public double Calories { get; set; }
}

public class ChartViewModel
{
    public List<Model> Data { get; set; }
    
    public ChartViewModel()
    {
        Data = new List<Model>()
        {
            new Model { FoodName = "Sweet treats", Calories = 250 },
            new Model { FoodName = "Cheese", Calories = 402 },
            new Model { FoodName = "Vegetables", Calories = 65 },
            new Model { FoodName = "Fish", Calories = 206 },
            new Model { FoodName = "Fruits", Calories = 52 },
            new Model { FoodName = "Rice", Calories = 130 }
        };
    }
}

Code-Behind (C#):

using Syncfusion.UI.Xaml.Charts;
using Microsoft.UI.Xaml;

public sealed partial class MainWindow : Window
{
    public MainWindow()
    {
        this.InitializeComponent();
        
        // Alternative: Create chart programmatically
        SfPyramidChart chart = new SfPyramidChart();
        ChartViewModel viewModel = new ChartViewModel();
        chart.DataContext = viewModel;
        chart.SetBinding(SfPyramidChart.ItemsSourceProperty, 
            new Binding() { Path = new PropertyPath("Data") });
        chart.XBindingPath = "FoodName";
        chart.YBindingPath = "Calories";
        chart.Header = "Food Nutrition Pyramid";
        chart.Legend = new ChartLegend();
        chart.EnableTooltip = true;
        chart.ShowDataLabels = true;
        
        this.Content = chart;
    }
}

Common Patterns

Pattern 1: Custom Color Palette

<Grid>
    <Grid.Resources>
        <BrushCollection x:Key="customColors">
            <SolidColorBrush Color="#4dd0e1"/>
            <SolidColorBrush Color="#26c6da"/>
            <SolidColorBrush Color="#00bcd4"/>
            <SolidColorBrush Color="#00acc1"/>
            <SolidColorBrush Color="#0097a7"/>
        </BrushCollection>
    </Grid.Resources>
    
    <chart:SfPyramidChart Palette="Custom"
                          PaletteBrushes="{StaticResource customColors}"
                          ItemsSource="{Binding Data}"
                          XBindingPath="Category"
                          YBindingPath="Value"/>
</Grid>

Pattern 2: Interactive Pyramid with Selection

<chart:SfPyramidChart ItemsSource="{Binding Data}"
                      XBindingPath="Category"
                      YBindingPath="Value"
                      SelectionBehavior="SelectSingle">
    
    <chart:SfPyramidChart.SelectionBrush>
        <SolidColorBrush Color="#FF6B6B"/>
    </chart:SfPyramidChart.SelectionBrush>
    
</chart:SfPyramidChart>

Pattern 3: Exploding Segment on Click

<chart:SfPyramidChart ItemsSource="{Binding Data}"
                      XBindingPath="Category"
                      YBindingPath="Value"
                      ExplodeOnClick="True"
                      ExplodeRadius="10"/>

Pattern 4: Gradient-Styled Pyramid

<Grid>
    <Grid.Resources>
        <BrushCollection x:Key="gradientColors">
            <LinearGradientBrush>
                <GradientStop Offset="1" Color="#FFE7C7"/>
                <GradientStop Offset="0" Color="#FCB69F"/>
            </LinearGradientBrush>
            <LinearGradientBrush>
                <GradientStop Offset="1" Color="#fadd7d"/>
                <GradientStop Offset="0" Color="#fccc2d"/>
            </LinearGradientBrush>
        </BrushCollection>
    </Grid.Resources>
    
    <chart:SfPyramidChart Palette="Custom"
                          PaletteBrushes="{StaticResource gradientColors}"
                          ItemsSource="{Binding Data}"
                          XBindingPath="Category"
                          YBindingPath="Value"/>
</Grid>
