   +----weka.gui.visualize.PlotData2D
public class PlotData2D
extends Object
This class is a container for plottable data. Instances form the primary data. An optional array of classifier/clusterer predictions (associated 1 for 1 with the instances) can also be provided.

Constructors

o PlotData2D 
 public PlotData2D(Instances insts)
Construct a new PlotData2D using the supplied instances

Parameters:
insts - the instances to use.

Methods

o addInstanceNumberAttribute 
 public void addInstanceNumberAttribute()
Adds an instance number attribute to the plottable instances,

o getPlotInstances 
 public Instances getPlotInstances()
Returns the instances for this plot

Returns:
the instances for this plot
o setPlotName 
 public void setPlotName(String name)
Set the name of this plot

Parameters:
name - the name for this plot
o getPlotName 
 public String getPlotName()
Get the name of this plot

Returns:
the name of this plot
o 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)
o 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)
o setShapeSize 
 public void setShapeSize(int ss[]) throws Exception
Set the shape sizes for the plot data

Parameters:
st - an array of integers specifying the size of data points
o setShapeSize 
 public void setShapeSize(FastVector ss) throws Exception
Set the shape sizes for the plot data

Parameters:
st - a FastVector of integers specifying the size of data points
o setConnectPoints 
 public void setConnectPoints(boolean cp[]) throws Exception
Set whether consecutive points should be connected by lines

Parameters:
cp - an array of boolean specifying which points should be connected to their preceeding neighbour.
o setConnectPoints 
 public void setConnectPoints(FastVector cp) throws Exception
Set whether consecutive points should be connected by lines

Parameters:
cp - a FastVector of boolean specifying which points should be connected to their preceeding neighbour.
o setCustomColour 
 public void setCustomColour(Color c)
Set a custom colour to use for this plot. This overides any data index to use for colouring. If null, then will revert back to the default (no custom colouring).

Parameters:
c - a custom colour to use for this plot or null (default---no colouring).

Parameters:
y - the y index
o setCindex 
 public void setCindex(int c)
Set the colouring index of the data

Parameters:
c - the colouring index
o getXindex 
 public int getXindex()
Get the currently set x index of the data

Returns:
the current x index
o getYindex 
 public int getYindex()
Get the currently set y index of the data

Returns:
the current y index
o getCindex 
 public int getCindex()
Get the currently set colouring index of the data

Returns:
the current colouring index
