Constructor Detail

UserScatterPlot

public UserScatterPlot(Domain d1,
               java.lang.String n1,
               Domain d2,
               java.lang.String n2)

This general constructor creates a new scatterplot correpsonding to specified domains and names. The x and y interval datasets are created to hold the data.

Parameters:

d1 - the domain of the x variable

n1 - the name of the x variable

d2 - the domain of the y variable

n2 - the name of the y variable

UserScatterPlot

public UserScatterPlot(Domain d1,
               Domain d2)

This special constructor creates a new user scatterplot with spcified domains and default names "x" and "y".

Parameters:

d1 - the domain of the x variable

d2 - the domain of the y variable

UserScatterPlot

public UserScatterPlot(Domain d,
               java.lang.String n1,
               java.lang.String n2)

This special constructur creates a new user scatterplot with common domain for the variables, and with specified names.

Parameters:

d - the common domain of the x and y variables

n1 - the name of the x variable

n2 - the name of the y variable

UserScatterPlot

public UserScatterPlot(Domain d)

This special constructor creates a new user scatterplot with a specified common domain for the variables and with default names "x" and "y".

Parameters:

d - the common domain of the x and y variables

UserScatterPlot

public UserScatterPlot()

This default constructor creates a new user scatterplot with default common domain (0, 1) with step size 0.1, and with default names "x" and "y".

Method Detail

paintComponent

public void paintComponent(java.awt.Graphics g)

This method paints the scatterplot. A horizontal green line is centered at the mean of the x data and extends one standard deviation in each direction.
