+  It is not useful to instantiate this class as it contains
+  static methods only.
+
+  \note If for some reason you are NOT using the
+  KDChartWidget class but calling the painting methods of KDChart directly,
+  you probably will also use the KDChartDataRegionList class:
+  This class is derived from QPtrList, so all of the Qt documentation
+  for this class is valid for KDChartDataRegionList too, e.g. freeing
+  of the pointers stored can either be done automatically or
+  manually - so PLEASE take the time to read the reference information for this class!
