public class ClassifierPanel
extends JPanel
implements Explorer.CapabilitiesFilterChangeListener, Explorer.ExplorerPanel, Explorer.LogHandler
```
0* This panel allows the user to select and configure a classifier, set the attribute of the current dataset to be used as the class, and evaluate the classifier using a number of testing modes (test on the training data, train/test on a percentage split, n-fold cross-validation, test on a separate split). The results of classification runs are stored in a result history so that previous results are accessible.

```
    Process a classifier's prediction for an instance and update a set of plotting instances and additional plotting info. plotInfo for nominal class datasets holds shape types (actual data points have automatic shape type assignment; classifier error data points have box shape type). For numeric class datasets, the actual data points are stored in plotInstances and plotInfo stores the error (which is later converted to shape size values)
    
    Parameters:
    
    toPredict - the actual data point
    
    classifier - the classifier
    
    eval - the evaluation object to use for evaluating the classifier on the instance to predict

    plotShape - additional plotting information (shape)
    
    plotSize - additional plotting information (size)
  - setUpVisualizableInstances
```
public static Instances setUpVisualizableInstances(Instances trainInstances)
```
    Sets up the structure for the visualizable instances. This dataset contains the original attributes plus the classifier's predictions for the class as an attribute called "predicted+WhateverTheClassIsCalled".
    
    Parameters:
    
    trainInstances - the instances that the classifier is trained on
    
    Returns:
    
    a new set of instances containing one more attribute (predicted class) than the trainInstances
