public class OHLCFactory

extends StockChartFactory

OHLCFactory implements a bar chart producer that can make OHLC styled charts from Open-High-Low-Close data.

Accepts OHLC, HLC, And HL data.

This factory inherits all of it's attribute and data operation logic from AxisFactory superclass, and most of it's rendering logic from StockChartFactory superclass.

Since:

JDK1.2

Method Detail

dup

public com.davisor.core.Dupable dup()

Duplicates this factory.

Specified by:

dup in interface com.davisor.core.Dupable

Overrides:

dup in class ColumnBarFactory

getLegendShape

public java.awt.Shape getLegendShape()

Gets the legend symbol shape preferred by this factory.

This factory prefers a simplistic OHLC-symbol. If its cretation fails, calls super class implementation.

Overrides:

getLegendShape in class ChartFactory

Returns:

a Shape instance
