protectedpure virtual

Called to calculate bar geometry params. Must be implemented by derivate classes.

Parameters

dataset	dataset
item	item index
serie	serie index
width	output for bar width
shift	output for bar shift
base	output for bar base
value	output for bar value

Implemented in LayeredBarType, StackedBarType, and NormalBarType.
