- - ### Constructor Detail

    - #### InstancesSummaryPanel

          public InstancesSummaryPanel()

      Creates the instances panel with no initial instances.

  - ### Method Detail

    - #### setShowZeroInstancesAsUnknown

          public void setShowZeroInstancesAsUnknown(boolean zeroAsUnknown)

      Set whether to show zero instances as unknown (i.e. "?" rather than zero). This is useful if header information has been read and the instances themselves will be loaded incrementally.
      Parameters:
        `zeroAsUnknown` - true if zero instances will be displayed as "unknown", i.e. "?"

    - #### getShowZeroInstancesAsUnknown

          public boolean getShowZeroInstancesAsUnknown()

      Get whether to show zero instances as unknown (i.e. "?" rather than zero). This is useful if header information has been read and the instances themselves will be loaded incrementally.
      Returns:
        true if zero instances will be displayed as "unknown", i.e. "?"

    - #### setInstances

          public void setInstances(Instances inst)

      Tells the panel to use a new set of instances.
      Parameters:
        `inst` - a set of Instances

    - #### main

          public static void main(java.lang.String[] args)

      Tests out the instance summary panel from the command line.
      Parameters:
        `args` - optional name of dataset to load
