Blazor Pivot Table Example - Sparkline Chart

This sample demonstrates how to embed Sparkline charts within Pivot Table cells to visually highlight trends and performance comparisons in sales data at a glance.

The Sparkline charts are rendered by capturing relevant cell values during the CellTemplate event and are inserted into the Pivot Table's grand total cells after full rendering via the EnginePopulated event.

A built-in dropdown in the grand total column header allows dynamic switching between different Sparkline types at runtime:

• Line - Displays trends with a continuous line visualization.
• Column - Shows values as vertical bars for easy comparison.
• Area - Highlights magnitude with a filled line chart representation.
• WinLoss - Visualizes binary outcomes without exposing exact numerical values.

Embedding the chart-type selector within the header maintains a compact and intuitive interface, enabling seamless visual analysis with minimal performance overhead.
