用 Sankey 系列圖表追蹤資料流

TeeChart Pro VCL/FMX by Steema Software is a comprehensive charting library designed for Embarcadero's Delphi and C++Builder environments, supporting both the VCL (Visual Component Library) and FMX (FireMonkey) frameworks. It provides developers with a rich set of chart types, advanced data visualization tools, and interactive features to build visually compelling and data-intensive applications across Windows, macOS, iOS, and Android. With support for real-time charting, custom drawing, statistical functions, and export capabilities, TeeChart Pro is tailored for high-performance applications that demand precise and dynamic chart displays.

The TeeChart Pro VCL/FMX 2025 (Build 2025.45.250910) update introduces the Sankey Series chart type, which gives developers a new tool for visualizing flows and relationships in data (e.g. movement of quantities between states, split‑paths, or aggregations). It enables rendering of nodes and links whose thickness is proportional to the magnitude of the flow, allowing you to more directly see how values distribute and split across paths. This enhances insight into complex datasets in ways that standard bar, line, or pie charts cannot, helping in diagnosing bottlenecks, tracing resource paths, or modelling multi‑stage processes with clarity.
