Quick Start Example

Minimal Pivot Chart Implementation

using System;
using System.Windows.Forms;
using Syncfusion.Windows.Forms.PivotChart;
using Syncfusion.PivotAnalysis.Base;

namespace PivotChartDemo
{
    public partial class Form1 : Form
    {
        private PivotChart pivotChart1;

        public Form1()
        {
            InitializeComponent();

            // Initialize Pivot Chart
            pivotChart1 = new PivotChart();
            pivotChart1.Dock = DockStyle.Fill;

            // Bind data source
            pivotChart1.ItemSource = ProductSales.GetSalesData();

            // Configure Pivot Axis (hierarchical structure)
            pivotChart1.PivotAxis.Add(new PivotItem
            {
                FieldMappingName = "Product",
                TotalHeader = "Total"
            });
            pivotChart1.PivotAxis.Add(new PivotItem
            {
                FieldMappingName = "Country",
                TotalHeader = "Total"
            });
            pivotChart1.PivotAxis.Add(new PivotItem
            {
                FieldMappingName = "State",
                TotalHeader = "Total"
            });

            // Configure Pivot Legend (series categorization)
            pivotChart1.PivotLegend.Add(new PivotItem
            {
                FieldMappingName = "Date",
                TotalHeader = "Total"
            });

            // Configure Calculations (data aggregation)
            pivotChart1.PivotCalculations.Add(new PivotComputationInfo
            {
                FieldName = "Quantity",
                Format = "#,##0"
            });

            // Set chart type
            pivotChart1.ChartTypes = PivotChartTypes.Column;

            // Enable drill-down
            pivotChart1.AllowDrillDown = true;

            // Add to form
            this.Controls.Add(pivotChart1);
        }
    }
}

Common Patterns

Pattern 1: Binding to IEnumerable Collection

using System.Collections.Generic;

// Data model
public class SalesData
{
    public string Product { get; set; }
    public string Region { get; set; }
    public string Quarter { get; set; }
    public int Quantity { get; set; }
    public decimal Amount { get; set; }
}

// Create and bind data
private void BindPivotChart()
{
    List<SalesData> salesList = new List<SalesData>
    {
        new SalesData { Product = "Laptop", Region = "North", Quarter = "Q1", Quantity = 50, Amount = 50000 },
        new SalesData { Product = "Laptop", Region = "South", Quarter = "Q1", Quantity = 40, Amount = 40000 },
        new SalesData { Product = "Mouse", Region = "North", Quarter = "Q1", Quantity = 200, Amount = 6000 },
        // Add more data...
    };

    pivotChart1.ItemSource = salesList;

    // Configure fields
    pivotChart1.PivotAxis.Add(new PivotItem { FieldMappingName = "Product", TotalHeader = "Total" });
    pivotChart1.PivotLegend.Add(new PivotItem { FieldMappingName = "Quarter", TotalHeader = "Total" });
    pivotChart1.PivotCalculations.Add(new PivotComputationInfo
    {
        FieldName = "Amount",
        Format = "C",
        SummaryType = SummaryType.DoubleTotalSum
    });
}

Pattern 2: Switching Chart Types Dynamically

// Add buttons or menu items to switch chart types
private void btnLineChart_Click(object sender, EventArgs e)
{
    pivotChart1.ChartTypes = PivotChartTypes.Line;
}

private void btnColumnChart_Click(object sender, EventArgs e)
{
    pivotChart1.ChartTypes = PivotChartTypes.Column;
}

private void btnAreaChart_Click(object sender, EventArgs e)
{
    pivotChart1.ChartTypes = PivotChartTypes.Area;
}

private void btnStackingColumn_Click(object sender, EventArgs e)
{
    pivotChart1.ChartTypes = PivotChartTypes.StackingColumn;
}

Pattern 3: Hierarchical Drill-Down Configuration

// Enable drill-down with multiple hierarchy levels
private void ConfigureDrillDown()
{
    pivotChart1.AllowDrillDown = true;

    // Define hierarchy: Category → Product → Region → State
    pivotChart1.PivotAxis.Clear();
    pivotChart1.PivotAxis.Add(new PivotItem
    {
        FieldMappingName = "Category",
        TotalHeader = "All Categories"
    });
    pivotChart1.PivotAxis.Add(new PivotItem
    {
        FieldMappingName = "Product",
        TotalHeader = "All Products"
    });
    pivotChart1.PivotAxis.Add(new PivotItem
    {
        FieldMappingName = "Region",
        TotalHeader = "All Regions"
    });
    pivotChart1.PivotAxis.Add(new PivotItem
    {
        FieldMappingName = "State",
        TotalHeader = "All States"
    });
}

Pattern 4: Real-Time Data Updates

// Enable automatic updates when data changes
private void ConfigureRealTimeUpdates()
{
    // Enable automatic chart updates
    pivotChart1.EnableUpdating = true;

    // Bind to observable collection or implement INotifyPropertyChanged
    var salesData = new BindingList<SalesData>(GetSalesData());
    pivotChart1.ItemSource = salesData;

    // Now any changes to salesData will automatically update the chart
}

// For bulk updates, use BeginUpdate/EndUpdate
private void BulkDataUpdate()
{
    pivotChart1.BeginUpdate();

    try
    {
        // Perform multiple data operations
        var data = (BindingList<SalesData>)pivotChart1.ItemSource;
        for (int i = 0; i < 100; i++)
        {
            data.Add(new SalesData { /* ... */ });
        }
    }
    finally
    {
        pivotChart1.EndUpdate(); // Chart updates once after all changes
    }
}

Pattern 5: Multiple Calculations with Formatting

// Display multiple aggregated values with custom formatting
private void ConfigureMultipleCalculations()
{
    pivotChart1.PivotCalculations.Clear();

    // Total quantity
    pivotChart1.PivotCalculations.Add(new PivotComputationInfo
    {
        FieldName = "Quantity",
        Format = "#,##0",
        SummaryType = SummaryType.DoubleTotalSum,
        FieldHeader = "Total Qty"
    });

    // Total amount (currency)
    pivotChart1.PivotCalculations.Add(new PivotComputationInfo
    {
        FieldName = "Amount",
        Format = "C2",
        SummaryType = SummaryType.DoubleTotalSum,
        FieldHeader = "Total Amount"
    });

    // Average price
    pivotChart1.PivotCalculations.Add(new PivotComputationInfo
    {
        FieldName = "UnitPrice",
        Format = "C2",
        SummaryType = SummaryType.DoubleAverage,
        FieldHeader = "Avg Price"
    });
}

Key Methods

Common Use Cases

Business Intelligence Dashboard

• Visualize sales data by product, region, and time period
• Drill down from yearly to quarterly to monthly views
• Compare multiple metrics (quantity, revenue, profit)

Financial Analysis

• Display financial data across departments, periods, and categories
• Analyze budget vs. actual spending with hierarchical drill-down
• Visualize profit/loss trends across business units

Marketing Analytics

• Analyze campaign performance by channel, region, and time period
• Compare multiple KPIs (impressions, clicks, conversions)
• Drill down from campaign level to ad group level

Performance Considerations

1. Use BeginUpdate/EndUpdate for bulk data operations to prevent multiple redraws
2. Limit hierarchy depth - 3-4 levels is optimal for performance and usability
3. Filter data before binding rather than binding entire dataset
4. Consider data volume - for very large datasets (100k+ rows), pre-aggregate data

Best Practices

1. Always register license key before creating pivot chart control
2. Define clear hierarchy in PivotAxis for intuitive drill-down
3. Use descriptive TotalHeader values for better user understanding
4. Format calculations appropriately (currency, percentages, numbers)
5. Enable drill-down only if data has meaningful hierarchical structure
6. Use grouping bar or field list for interactive user exploration
