Constructor Detail

DataFunction

public DataFunction(DatasetManager input)

Constructs a DataFunction for the specified input data.

Parameters:

input - the input data

DataFunction

public DataFunction(DatasetManager input,
                    java.lang.String name,
                    java.lang.String expression)

Constructs a DataFunction for the specified input data, name and expression.

Parameters:

input - the input data

name -

expression -

Method Detail

setExpression

public void setExpression(java.lang.String e)

Sets the expression.

Parameters:

e - the expression string

getExpression

public java.lang.String getExpression()

Gets the expression.

Returns:

the expression string

setYColumnName

public void setYColumnName(java.lang.String name)

Sets the y-column name (ie the function name).

Parameters:

name - the name

getInputString

public java.lang.String getInputString()

Gets the current input string. If the last attempt to set the function was unsuccessful, this is different from the function string.

Returns:

the input string

refreshFunctionData

public void refreshFunctionData()

Refreshes the data points.

toString

public java.lang.String toString()

Description copied from class: Dataset

Creates a string representation of the data.

Overrides:

toString in class Dataset

Returns:

the name of this DataFunction

append

public void append(double x,
                   double y)

Overrides Dataset methods. DatasetFunction manages its own data.

Overrides:

append in class Dataset

append

public void append(double x,
                   double y,
                   double dx,
                   double dy)

Description copied from class: Dataset

Appends a data point and its uncertainty to the Dataset.

Overrides:

append in class Dataset

append

public void append(double[] x,
                   double[] y)

Description copied from class: Dataset

Appends (x,y) arrays to the Dataset. Any y value of Double.NaN is treated as null in plots and tables.

Overrides:

append in class Dataset

public void append(double[] x,
                   double[] y,
                   double[] dx,
                   double[] dy)

Description copied from class: Dataset

Appends arrays of data points and uncertainties to the Dataset.

Overrides:

append in class Dataset

Description copied from class: Dataset

Clear all data from this Dataset.

Overrides:

clear in class Dataset
