Class CandlestickHollowRenderer

java.lang.Object

com.arbergashi.charts.render.BaseRenderer

com.arbergashi.charts.render.financial.CandlestickHollowRenderer

All Implemented Interfaces:

ChartRenderer

public final class CandlestickHollowRenderer
extends BaseRenderer

Hollow Candlestick renderer (specialized variant).

Expected point encoding:

• x = time/index
• weight = open
• min = low
• max = high
• y = close

Performance policy:

• No allocations in the hot drawing loop (no Point2D creation).
• For very dense datasets, switches to a level-of-detail (LOD) representation by aggregating into per-pixel OHLC buckets.
