  \class KDChartPropertySet KDChartPropertySet.h
  \brief Property settings of a single KDChart data cell.

  \note The property settings feature currently is supported by
  normal (== not 3-dimensional!) Line Charts only. Future releases
  of KDChart will offer a rich set of options to use cell-specific
  properties for other chart types as well...

  The KDChartPropertySet class stores several settings to be
  used by the painter classes to decide how to visualize the
  respective data cell.
  Each of the settings may be specified either by giving a
  value for it or by using the ID of another KDChartPropertySet
instance: If the later the value of that instance is used
instead of the value that is stored locally.
