Detailed Description

ECS component that defines a logical coordinate offset.

This component stores a 2D offset (in logical units) applied to graphical elements such as axes, curves, titles, labels and data points. It allows changing the visual reference frame without affecting pixel-based positioning.

Usage Examples:

• With offset = ( 0, 0 ), logical coordinates are drawn as-is.
• With offset = ( -20, 0 ), the visual origin is shifted 20 units to the right.

The offset is often combined with the origin and scale to compute actual pixel positions.
