Title: Added missing "bar" attribute to several charts

I've added the "bar" attribute to the four charts I could find which used it.

Name
bar.groupWidth

Type
number or string

Default
The golden ratio, approximately '61.8%'.

Description
The width of a group of bars, specified in either of these formats:
Pixels (e.g. 50).
Percentage of the available width for each group (e.g. '20%'), where '100%' means that groups have no space between them.
