Class TernaryContourRenderer

java.lang.Object

com.arbergashi.charts.render.BaseRenderer

com.arbergashi.charts.render.specialized.TernaryContourRenderer

All Implemented Interfaces:

ChartRenderer

public class TernaryContourRenderer
extends BaseRenderer

Ternary Contour Renderer - extends ternary plot with contour/heatmap characteristics.

Performance contract: The contour effect is rendered using a fixed number of bands and alpha compositing (no per-band Color allocation). This ensures that even large datasets can be rendered efficiently without excessive memory usage.
