AbsoluteDashing

AbsoluteDashing[{d1,d2,…}] is a graphics directive which specifies that lines which follow are to be drawn dashed, with successive segments having absolute lengths d1, d2, … (repeated cyclically). 

AbsoluteDashing[d] is equivalent to AbsoluteDashing[{d,d}]. 

AbsoluteDashing[{d1,d2,…},offset] offsets the dashes by offset.

AbsoluteDashing[{d1,d2,…},offset,capform] sets the CapForm for individual dashes to capform.
