Updates in 2025.2

Features

• 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.

Framework Improvements

• SVG Images:
  • Improved import of linear gradients.
