+BarChart displays a number of bars in a chart. Each bar can be divided in segments with different
+colors. The maximum number of segments is 12. The size of each segment corresponds an to an array
+of float values, where each element in the array states the segments size in different bars.
+
+The properties fill, fillcolor, bordercolor etc. states properties for the background rectangle.
+The properties for the bars and segments are stated in the object editor.
+A bar is created by selecting BarChart in the subgraph palette, 'Analog/BarChart', and clicking 
+MB2 in the working area.
