Constructor Detail

AveragingDataSet

public AveragingDataSet(String name)

Parameters:

name - data set name

AveragingDataSet

public AveragingDataSet(String name,
                        int fuzzyCount)

Parameters:

name - data set name

fuzzyCount - binning accuracy @see #setFuzzyCount

Method Detail

getFuzzyCount

public int getFuzzyCount()

Gets the fuzzy count.

Returns:

fuzzy count

setFuzzyCount

public void setFuzzyCount(int fuzzyCount)

Sets the fuzzy count. The fuzzy count allows for a mismatch in the data count of the datasets added to the average. Datasets will be added if the size difference is less or equal to the fuzzy count. In case of a mismatch in size, the longer dataset will be truncated to the shorter one.

Parameters:

fuzzyCount - the fuzzy count

getAverageSize

public int getAverageSize()

Returns:

number of data sets that are supposed to be averaged

setAverageSize

public void setAverageSize(int avgCount)

Parameters:

avgCount - number of data sets that are supposed to be averaged

getAverageCount

public int getAverageCount()

Returns:

number of data sets that have been averaged

clear

public void clear()

clear all data

add

public void add(DataSet ds)

Parameters:

ds - new DataSet to be added to average

getDataCount

public int getDataCount()

Description copied from interface: DataSet

Get the number of data points in the data set

Returns:

the number of data points

getDataCount

public int getDataCount(double xmin,
                        double xmax)

Description copied from class: AbstractDataSet

Gets the number of data points in the range xmin to xmax.

Specified by:

getDataCount in interface DataSet

Overrides:

getDataCount in class AbstractDataSet<AveragingDataSet>

Parameters:

xmin - the lower end of the range

xmax - the upper end of the range

Returns:

the number of data points

getYValues

public double[] getYValues()

Returns:

the y value array

getX

public double getX(int i)

Description copied from interface: DataSet

Gets the x value of the data point with the index i

Parameters:

i - the index of the data point

Returns:

the x value

getY

public double getY(int i)

Description copied from interface: DataSet

Gets the y value of the data point with the index i

Parameters:

i - the index of the data point

Returns:

the y value

getXIndex

public int getXIndex(double x)

Description copied from class: AbstractDataSet

Gets the index of the data point closest to the given x coordinate. The index returned may be less then zero or larger the the number of data points in the data set, if the x coordinate lies outside the range of the data set.

Specified by:

getXIndex in interface DataSet

Overrides:

getXIndex in class AbstractDataSet<AveragingDataSet>

Parameters:

x - the x position of the data point

Returns:

the index of the data point

getXMin

public double getXMin()

Description copied from class: AbstractDataSet

Gets the minimum x value of the data set.

Specified by:

getXMin in interface DataSet

Overrides:

getXMin in class AbstractDataSet<AveragingDataSet>

Returns:

minimum x value

getXMax

public double getXMax()

Description copied from class: AbstractDataSet

Gets the maximum x value of the data set.

Specified by:

getXMax in interface DataSet

Overrides:

getXMax in class AbstractDataSet<AveragingDataSet>

Returns:

maximum x value

getYMin

public double getYMin()

Description copied from class: AbstractDataSet

Gets the minimum y value of the data set.

Specified by:

getYMin in interface DataSet

Overrides:

getYMin in class AbstractDataSet<AveragingDataSet>

Returns:

minimum y value

getYMax

public double getYMax()

Description copied from class: AbstractDataSet

Gets the maximum y value of the data set.

Specified by:

getYMax in interface DataSet

Overrides:

getYMax in class AbstractDataSet<AveragingDataSet>

Returns:

maximum y value

getStyle

public String getStyle(int index)

Description copied from interface: DataSet

A string representation of the CSS style associated with this specific DataSet data point. @see #getStyle()

Parameters:

index - the index of the specific data point

Returns:

user-specific data set style description (ie. may be set by user)
