<DD>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)
