All Implemented Interfaces:

ChartRenderer

public class StatisticalErrorBarRenderer
extends BaseRenderer

Statistical Error Bar Renderer (JDK 25 Standard). Extends plots with horizontal and vertical error bars. Supports standard deviation, confidence intervals and custom ranges. Data Mapping (ChartPoint): x → Central X position y → Central Y position min → Lower bound (Y) for vertical error max → Upper bound (Y) for vertical error weight → Horizontal error extent (+/-) from x Features: - Vertical and horizontal error bars - Customizable cap width - High-DPI support - Clipping optimization
