Field Detail

m_useCustomColour

public boolean m_useCustomColour

Custom colour for this plot

m_customColour

public Color m_customColour

m_displayAllPoints

public boolean m_displayAllPoints

Display all points (ie. those that map to the same display coords)

Constructor Detail

PlotData2D

public PlotData2D(Instances insts)

Construct a new PlotData2D using the supplied instances

Parameters:

insts - the instances to use.

Method Detail

addInstanceNumberAttribute

public void addInstanceNumberAttribute()

Adds an instance number attribute to the plottable instances,

getPlotInstances

public Instances getPlotInstances()

Returns the instances for this plot

Returns:

the instances for this plot

setPlotName

public void setPlotName(String name)

Set the name of this plot

Parameters:

name - the name for this plot

getPlotName

public String getPlotName()

Get the name of this plot

Returns:

the name of this plot

setPlotNameHTML

public void setPlotNameHTML(String name)

Set the plot name for use in a tool tip text.

Parameters:

name - the name of the plot for potential use in a tool tip text (may use html).

getPlotNameHTML

public String getPlotNameHTML()

Get the name of the plot for use in a tool tip text. Defaults to the standard plot name if it hasn't been set.

Returns:

the name of this plot (possibly in html) for use in a tool tip text.

setShapeType

public void setShapeType(int[] st)
                  throws Exception

Set the shape type for the plot data

Parameters:

st - an array of integers corresponding to shape types (see constants defined in Plot2D)

Throws:

Exception

setShapeType

public void setShapeType(FastVector st)
                  throws Exception

Set the shape type for the plot data

Parameters:

st - a FastVector of integers corresponding to shape types (see constants defined in Plot2D)

Throws:

Exception

setShapeSize

public void setShapeSize(int[] ss)
                  throws Exception

Set the shape sizes for the plot data

Parameters:

ss - an array of integers specifying the size of data points

Throws:

Exception

setShapeSize

public void setShapeSize(FastVector ss)
                  throws Exception

Set the shape sizes for the plot data

Parameters:

ss - a FastVector of integers specifying the size of data points

Throws:

Exception

setConnectPoints

public void setConnectPoints(boolean[] cp)
                      throws Exception
