  • Method Details

    • getZoneCount

      int getZoneCount()
      Returns the number of zones in this gang.
      Returns:
      zone count
    • getZonePlotBounds

      Rectangle getZonePlotBounds(int iz)
      Returns the data bounds for a given zone. This is the region within which data can be plotted, it does not include space for external axis labels etc.
      Parameters:
      iz - index of zone
      Returns:
      plot bounds for zone
    • getNavigationZoneIndex

      int getNavigationZoneIndex(Point pos)
      Returns the zone index for the zone to which navigation gestures referenced at a particular graphics position should be delegated.

      In most cases, if the position falls within the data bounds of a given zone, that zone index will be returned, but if the position falls outside of any zones, it may still be useful to return the index of a zone whose navigator can take care of it. A negative value may be returned to indicate no zone, but generally it's better to indicate some zone rather than none.

      Parameters:
      pos - graphics position relating to user navigation gesture
      Returns:
      index of zone for navigation actions, or negative for no zone
