      org.mov.chart.graph.CountbackLineGraph

All Implemented Interfaces:

Graph

public class CountbackLineGraph
extends AbstractGraph

3 Bar Nett Countback lines. This graph draws a single across a price value which indicates a buy signal if used with highs in a down trend and a sell signal with lows in a new uptrend.

CountbackLineGraph

public CountbackLineGraph(GraphSource low,
                          GraphSource high,
                          GraphSource close)

Parameters:

source - the source to create a moving average 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)

Description copied from class: AbstractGraph

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

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.
