Class HorizonChartRenderer

java.lang.Object

com.arbergashi.charts.render.BaseRenderer

com.arbergashi.charts.render.specialized.HorizonChartRenderer

All Implemented Interfaces:

ChartRenderer

public class HorizonChartRenderer
extends BaseRenderer

Legacy horizon chart renderer.

This class is kept for backward compatibility but is no longer auto-registered (see HorizonRenderer). It is still safe to instantiate directly.

Performance notes:

• Uses allocation-free pixel mapping via PlotContext.mapToPixel(double, double, double[]).
• Reuses arrays and cached colors to avoid GC pressure in paintComponent.
