- A callable function, which can be either the name of a function or an anonymous function itself.

RGBA colours, and colour names. SVG uses
"none"for no colour, which generally leaves things transparent.

Opacity of bar side overlay.
This option sets the opacity of the overlay that is drawn over the top of the 3D
bar side area to change its appearance. The default value
0.5 means that the
overlay is 50% opaque, and the default black colour means it darkens the side
of the bar while allowing the colour, pattern or gradient underneath to show
A value of
0 disables the overlay completely.
