2025 December 11 - Announcing Nevron Open Vision for .NET 2025.2

Wilmington, Delaware — Dec 11, 2025

The Nevron Team is pleased to announce the official release of Nevron Open Vision for .NET 2025.2, featuring leading Data Visualization and User Interface components for Blazor, WPF, WinForms, and Mac. Below is a list of the new features and improvements included in this release:

NOV Chart for .NET Improvements:

• 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..

NOV Diagram for .NET 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.

NOV UI for .NET Improvements

• 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.

Framework Improvements

• SVG Images
  Improved import of linear gradients.
