Quick Start Example ### Minimal Pivot Chart Implementation ```csharp 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 ```csharp 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 ```csharp // 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 ```csharp // 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 ```csharp // 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 ```csharp // 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 Properties and Methods ### Core Properties | Property | Type | Description | |----------|------|-------------| | `ItemSource` | object | Data source (IEnumerable or DataTable) | | `PivotAxis` | PivotItemCollection | Fields for chart axis (hierarchical) | | `PivotLegend` | PivotItemCollection | Fields for legend/series | | `PivotCalculations` | PivotComputationInfoCollection | Calculation/aggregation fields | | `ChartTypes` | PivotChartTypes | Chart type (Line, Column, Area, etc.) | | `AllowDrillDown` | bool | Enable drill-down/drill-up operations | | `EnableUpdating` | bool | Auto-update when data changes | ### PivotItem Properties | Property | Type | Description | |----------|------|-------------| | `FieldMappingName` | string | Name of data field to bind | | `TotalHeader` | string | Header text for total/aggregate row | | `FieldHeader` | string | Display header for the field | ### PivotComputationInfo Properties | Property | Type | Description | |----------|------|-------------| | `FieldName` | string | Name of field to calculate | | `Format` | string | Number format string | | `SummaryType` | SummaryType | Aggregation type (Sum, Average, Count, etc.) | | `FieldHeader` | string | Display name for calculation | ### Key Methods | Method | Description | |--------|-------------| | `BeginUpdate()` | Suspend chart updates for bulk operations | | `EndUpdate()` | Resume chart updates and refresh | | `Refresh()` | Manually refresh the chart | ## 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
