DevExpress BI Dashboard v25.1 現在支援導出可縮放向量圖像以進行列印、共用或文件嵌入。

DevExpress BI Dashboard (part of DevExpress Universal) empowers you to craft interactive dashboards for desktop, web and mobile applications. It provides a visual designer for building dashboards without writing code, allowing you to drag-and-drop various data visualization widgets onto the canvas. These widgets connect to your data sources and update dynamically, offering real-time insights to end users. The tool also supports customization through properties and events, enabling you to tailor the look and feel of the dashboards to perfectly integrate with your application's design.

The DevExpress BI Dashboard v25.1 update adds support for exporting entire dashboards, specific items, or tab pages to Scalable Vector Graphics (SVG) format. This enhancement allows users and analysts to create resolution-independent, high-quality exports that maintain clarity at any size. SVG output is particularly useful for printed reports, shared presentations, or integration into documentation, where visual fidelity is essential.

在您的 .NET 財務應用程式中集成點數圖表

7月 25, 2025
在不基於時間混亂的情況下繪製價格驅動趨勢，點圖和圖形圖使用簡單的 X 和 O 邏輯揭示關鍵的市場走勢。

A point and figure (P&F) chart is a financial charting technique used to track price movements by plotting directional changes in price without reference to time. It focuses exclusively on significant price changes, filtering out minor fluctuations to highlight clear trends and reversals. Instead of plotting prices continuously, it uses columns of Xs and Os to represent rising and falling prices, respectively, based on predefined price increments. This chart type provides a straightforward view of supply and demand dynamics, making it particularly effective for identifying support and resistance levels, breakout patterns, and trend direction. Its simplicity helps traders and analysts focus on essential price action, reducing the noise found in traditional time-based charts.

Several .NET charting components provide you with point and figure charts, including:

  • ComponentOne Charts for WPF (part of ComponentOne Studio Enterprise by MESCIUS) offers point and figure charts with configurable box sizes and reversal settings for clear trend analysis.
  • Nevron Chart for ASP.NET (part of Nevron Chart for .NET) provides financial web applications with point and figure charts, supporting price filtering and reversal logic.
  • Chart FX 8 Windows Forms (part of Chart FX 8 by Software FX) includes point and figure charts to visualize price trends, support/resistance levels, and reversals without time-based noise.
  • TeeChart .NET for Blazor by Steema Software includes point and figure support to plot non-time-based price movements for financial analysis.
  • Syncfusion WinForms Chart (part of Syncfusion Essential Studio Enterprise) facilitates the use of point and figure charts in Windows desktop applications to analyze price data.
