This is a demo widget programmed as a learning experience...
hallo erstmal...
a simple PieChart,
(zeigt ein Tortendiagramm, wobei die Stücke jedoch nicht essbar sind.)
The model is a collection of chart description items,
each being a dictionary filled with entries for:
#value aNumber the numeric value
#color aColor the color
see example on how to fill such a chartDescription model.
[instance variables:]
middlePoint, only for the point in the middle => therefore middlepoint
radX radian for x-coordinate
radY radian for y-coordinate
anzahl number of pie-pieces
summe result of all values
aod Array of Dictionaries
aoHilf Array with help coordinates
foregroundColor text color for percent displaying
backgroundColor background color of pie chart
label1 name of pie chart
BarChartWidget
