Class JASHistData

java.lang.Object
  java.util.Observable
      jas.hist.JASHistData

All Implemented Interfaces:

Observer

public abstract class JASHistData
extends Observable
implements Observer

This class is returned whenever a DataSource is added to a JASHist It supports making the data visible/invisible, and controlling the style (color etc) in which the data is shown.

Constructor Detail

JASHistData

public JASHistData()

Only used for object serialization, do not call

Method Detail

show

public void show(boolean show)

Controls the visibility of the associated DataSource Only listens to changes in DataSources if visible

Parameters:

show - true if the DataSource should be visible

setShowStatistics

public void setShowStatistics(boolean show)

Controls whether statistics associated with this datasource should be shown

getShowStatistics

public boolean getShowStatistics()

setShowLegend

public void setShowLegend(boolean show)

Controls whether statistics associated with this datasource should be shown

getDataSource

public abstract DataSource getDataSource()

Get the DataSource associated with this JASHistData

Returns:

The associated DataSource

getFittableDataSource

public DataSource getFittableDataSource()

Get a DataSource suitable for using as the source for fit operations. In the case where the binning is set by the plot itself, this will differ from the orginal DataSource attached to the plot in that it reflects the current binning of the plot (remember a binned fit needs to be redone if the binning changes).

getDataSource()

getTitle

public abstract String getTitle()

Get the title of the associated DataSource

Returns:

The title

setStyle

public abstract void setStyle(JASHistStyle style)

Set a style for this data. The JASHistStyle object passed to this method must be appropriate for the corresponding DataSource, e.g. if the DataSource is a Rebinnable1DHistogramData then the JASHistStyle must be a JASHist1DStyle.

Parameters:

style - The style to be set

Throws:

IllegalArgumentException - If the style is not of the approriate type

getStyle

public abstract JASHistStyle getStyle()

Get the JASHistStyle associated with this DataSource

Returns:

The associated style

setYAxis

public void setYAxis(int i)

Sets which Y axis the data is plotted against.

Parameters:

axis - Either YAXIS_LEFT or YAXIS_RIGHT

getYAxis

public int getYAxis()

Get the y axis against which this data is plotted

Returns:

Either YAXIS_LEFT or YAXIS_RIGHT

setShowing

public void setShowing(boolean value)

Equivalent to show(boolean)

Parameters:

value - true if the corresponding DataSource should be visible

isShowing

public boolean isShowing()

Find out if this DayaSource is visible

Returns:

true if the corresponding DataSource is visible

toString

public String toString()

Overrides:

toString in class Object

setLegendText

public void setLegendText(String text)

Set the text for the legene entry corresponding to this data item

getLegendText

public String getLegendText()

setNormalization

public void setNormalization(Normalizer factor)

Set the normalization for this dataset.

Parameters:

factor - The normalization to apply, or null for no normalization

getNormalization

public Normalizer getNormalization()

setXBounds

public void setXBounds(double xmin,
                       double xmax)
