All Implemented Interfaces:

Graph

public class PointAndFigureGraph
extends AbstractGraph

Point and Figure graph. This graph draws a series of characters (X/O) mapping the general movement. A change in column shows a reversal such that price difference met the price scale.

Constructor Detail

PointAndFigureGraph

public PointAndFigureGraph(GraphSource source)

Create a new point and figure graph.

Parameters:

source - the source to create the point and figure from

Method Detail

render

public void render(java.awt.Graphics g,
                   java.awt.Color colour,
                   int xoffset,
                   int yoffset,
                   double horizontalScale,
                   double verticalScale,
                   double bottomLineValue,
                   java.util.List xRange)

Description copied from interface: Graph

Draw the graph.

Parameters:

g - the Graphics object to render to

colour - the colour the graph should be rendered in; override this if the graph should be drawn in a certain colour - such as a Moving Average graph

xoffset - the x offset in the graphics object where the graph starts

yoffset - the y offset in the graphics object where the graph starts

horizontalScale - horizontal scale factor; use this to convert between X value in the xRange to a cartesian coordinate x

verticalScale - vertical scale factor; use this to convert between Y value to a cartesian coordinate y

bottomLineValue - the Y value of the lowest line in the graph

xRange - a List of Comparable that contain the X values to plot

getToolTipText

public java.lang.String getToolTipText(java.lang.Comparable x,
                                       int y,
                                       int yoffset,
                                       double verticalScale,
                                       double bottomLineValue)

Get the tool tip text for the given X value and y coordinate.

Specified by:

getToolTipText in interface Graph

Overrides:

getToolTipText in class AbstractGraph

Parameters:

x - the X value

y - the y coordinate

yoffset - y offset from top of graph

verticalScale - vertical scale factor

bottomLineValue - the Y value of the lowest line in the graph

Returns:

the tool tip text for the default GraphSource

getHighestY

public double getHighestY(java.util.List x)

Description copied from class: AbstractGraph

Return the highest Y value in the given X range.

Specified by:

getHighestY in interface Graph

Overrides:

getHighestY in class AbstractGraph

Parameters:

x - range of X values

Returns:

the highest Y value of the default GraphSource

getLowestY

public double getLowestY(java.util.List x)

Description copied from class: AbstractGraph

Return the loweset Y value in the given X range.

Specified by:

getLowestY in interface Graph

Overrides:

getLowestY in class AbstractGraph

Parameters:

x - range of X values

Returns:

the lowest Y value of the default GraphSource

getName

public java.lang.String getName()

Return the name of this graph.

Returns:

Point and Figure

createPointAndFigureGraph

public static PFGraphable createPointAndFigureGraph(Graphable source,
                                                    double priceReversalScale,
                                                    double boxPriceScale)

Creates a new poing and figure graphable based on the given data source.

Rules of Point and Figure:

• X = Upmoves, O = DownMoves
• Stay in the same column until price changes direction, and then move one column to the right.
• Plot only prices which meet the price scale. A plot is marked regardless of the direction. If a direction change occurs, the affect is to move the column one to the right.

Parameters:

source - the graph source to average

Returns:

the graphable containing averaged data from the source

isPrimary

public boolean isPrimary()

Description copied from interface: Graph

Return whether the graph is a primary graph. Primary graphs will appear together in the top chart. Secondary graphs appear in their own charts which are added below. The day close graph is primary; while the day close graph is secondary.

Returns:

true if the graph is a primary graph

setSettings

public void setSettings(java.util.HashMap settings)

Description copied from class: AbstractGraph

Set the graph's user definable settings.

Specified by:

setSettings in interface Graph

Overrides:

setSettings in class AbstractGraph

Parameters:

settings - the new settings

getUI

public GraphUI getUI(java.util.HashMap settings)

Return the graph's user interface.

Specified by:

getUI in interface Graph

Overrides:

getUI in class AbstractGraph

Parameters:

settings - the initial settings

Returns:

user interface
