Description:

 This is a demo widget programmed as a learning experience...

 hallo erstmal...

 ChartDescription for a diagram, whose values are a model as like an array of dictionaries 
 so have a look at 'class - documentation - examples'
 This can be used beside a BarChartWidget or PieChartWidget as
 a legend (extracting its values from the same model).



 [instance variables:]
 xPos                x-Koordinate für Color-Punkt
 anzahl              number of pie-pieces
 summe               result of all values
 aod                 Array of Dictionaries
 aoHilf              Array für Hilfsvariablen der Winkelberechnungen
 foregroundColor     Textfarbe
 backgroundColor     Hintergrundfarbe
