Fetch binned data from remote data source. Also caches result to speed up subsequent requests for the same binned data.

Specified by:

rebin in interface Rebinnable2DHistogramData

getXMin

public double getXMin()

Specified by:

getXMin in interface Rebinnable2DHistogramData

getXMax

public double getXMax()

Specified by:

getXMax in interface Rebinnable2DHistogramData

getYMin

public double getYMin()

Specified by:

getYMax

public double getYMax()

Specified by:

getYMax in interface Rebinnable2DHistogramData

getXBins

public int getXBins()

Specified by:

getXBins in interface Rebinnable2DHistogramData

getYBins

public int getYBins()

Specified by:

getYBins in interface Rebinnable2DHistogramData

getXAxisType

public int getXAxisType()

Specified by:

getXAxisType in interface Rebinnable2DHistogramData

getYAxisType

public int getYAxisType()

Specified by:

getYAxisType in interface Rebinnable2DHistogramData

getXAxisLabels

public java.lang.String[] getXAxisLabels()

Specified by:

getXAxisLabels in interface Rebinnable2DHistogramData

getYAxisLabels

public java.lang.String[] getYAxisLabels()

Specified by:

getYAxisLabels in interface Rebinnable2DHistogramData

isRebinnable

public boolean isRebinnable()

Specified by:

isRebinnable in interface Rebinnable2DHistogramData

getTitle

public java.lang.String getTitle()

Description copied from interface: DataSource

Return the caption to be used in the legend for this data.

Specified by:

getTitle in interface DataSource

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getStatistics

public Statistics getStatistics()

Specified by:

getStatistics in interface HasStatistics

getStatisticNames

public java.lang.String[] getStatisticNames()

Specified by:

getStatisticNames in interface Statistics

Returns:

A list of statistic names

getStatistic

public double getStatistic(java.lang.String name)

Specified by:

getStatistic in interface Statistics

Returns:

The value for the statistic

getExtendedStatistic

public java.lang.Object getExtendedStatistic(java.lang.String name)

Description copied from interface: ExtendedStatistics

Returns an object corresponding to the named statistic. In general the statistic will be displayed by calling its toString method, however if a Format object has been defined for this class (how?) then it will be used instead. By default the following formatters are defined

java.lang.Double

jas2.util.ScientificFormat

jas2.util.DoubleWithError

jas2.util.ScientificFormat

If the method returns null, then the getStatistic() method from the subclass will be called instead. This simplifies the use of simple floating point statistics (no need to create a Double object for each one).

Specified by:

getExtendedStatistic in interface ExtendedStatistics

Parameters:

name - The name of the statistic to return

See Also:

ScientificFormat, DoubleWithError

getStyle

public JASHistStyle getStyle()

Description copied from interface: HasStyle

This method is called by the plot to determine what style to be used for a plot. It is the programmers responsibility to return the correct subclass of JASHistStyle corresponding to the type of data being implemented by the DataSource.

Specified by:

getStyle in interface HasStyle

Returns:

The style to be used, or null to use the default style.

See Also:

JASHist1DHistogramStyle, JASHist2DHistogramStyle, JASHistScatterPlotStyle

getNSlices

public int getNSlices()

Description copied from interface: HasSlices

Number of slices currently attached to plot

Specified by:

getNSlices in interface HasSlices

getSliceParameters

public SliceParameters getSliceParameters(int n)

Description copied from interface: HasSlices

Get the parameters of a slice. The SliceParameters can subsequently be changed to update the slice.

Specified by:

getSliceParameters in interface HasSlices

Parameters:

n - The index of the slice

Returns:

The Slice parameters of the slice with the specified index

getSlice

public Rebinnable1DHistogramData getSlice(int n)

Description copied from interface: HasSlices

Get the data corresponding to the slice. The data will be observable and will notify its observers if the slice changes, or the data from which the slice is derived changes

Specified by:

getSlice in interface HasSlices

Parameters:

n - The index of the slice

Returns:

The data resulting from the slice

canAddRemoveSlices

public boolean canAddRemoveSlices()

Specified by:

canAddRemoveSlices in interface HasSlices

                    double y,
                    double width,
                    double height,
                    double phi)

Description copied from interface: HasSlices

Create a new slice with the specified initial parameters

Specified by:

addSlice in interface HasSlices

Returns:

the index of the slice that was added

removeSlice

public void removeSlice(int n)

Description copied from interface: HasSlices

Remove a slice from the source

Specified by:

removeSlice in interface HasSlices

Parameters:

n - The index of the slice
