What is New in 2025 Vol 2

Chart Improvements

The new version of NOV Chart for .NET introduces several powerful features and enhancements:

• Fast Area Series – A new Fast Area series has been added to the existing set of fast series. It enables real-time visualization of extremely large datasets — up to millions of data points — in both 2D and 3D area charts. This is achieved through extensive GPU utilization for computational tasks. The series supports both 2D and 3D modes, as well as per–data-point color customization.
• Area Series Step Mode – The standard Area series now supports multiple step modes: Horizontal-Vertical (HV),Vertical-Horizontal (VH), and Horizontal-Vertical-Horizontal (HVH), allowing for more versatile data presentation.
• Best Visibility Dock Axis Anchors – New axis docking anchors automatically select the most suitable docking zone based on the current chart projection. Combined with the automatic chart wall visibility feature, this ensures maximum readability and visibility of the chart data.
• Table Scale – A new Table Scale type introduces categorical (ordinal) scaling that can display tabular data, with each column representing an axis category. This feature is especially useful for stacked charts or charts with multiple series.
• Palette Legend Item – the new Palette Legend Item allows gradient-based palette data to be displayed as a scale. This is particularly helpful in surface charts and heat maps where color gradients represent a third data dimension such as temperature or altitude.
• Bubble Size Legend Item – Commonly used in Bubble charts, this legend item provides a numeric reference for bubble sizes, represented as a series of circles originating from a common base.
• Interactivity Enhancements – New tools have been added for zooming and panning. Existing interactivity tools now support mouse wheel actions (e.g., wheel zooming) and keyboard interactions for smoother navigation.
• Custom Painting – Developers can now inject custom painting logic before or after the chart is rendered, providing advanced flexibility for tailored visualizations.
• Coordinate Transformations – New methods have been added for converting between logical, model, and view coordinates. This complements the custom painting feature, allowing developers to draw arbitrary content that aligns precisely with chart data on screen.
• Texture mapping – the control now supports texture mapping (gradients, images and patterns) to all chart objects in 3D..

Diagram Improvements

• Mermaid Flowchart Import – Support has been added for importing diagrams defined using the Mermaid flowchart syntax.
• Length Editors – Property editors for lengths now correctly account for the drawing scale of the page, ensuring accurate editing in scaled drawings.

Framework and UI Improvements

The latest version of NOV also includes several framework and UI updates:

• Font Awesome Integration – The new NFontSymbolShape attribute enables easy use of Font Awesome symbols, allowing icons to be embedded wherever standard widgets can appear.
• Wildcard Search in the Auto Complete Box - Added wildcard search mode to the auto complete box, for example "B?l*" to match "Belarus", "Belgium", "Bolivia", "Bulgaria".
• Item Hover - Support for item hover effect for list boxes, tree views and auto complete boxes.
• Non-Gregorian Calendar Support – The Calendar and DateBox widgets now support non-Gregorian calendars, including Persian, Hindi, and others.
• SVG Images - Improved import of linear gradients.
