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.

Details

  • Dash and offset lengths are measured in units of printer's points, equal before magnification to of an inch.
  • AbsoluteDashing[{}] specifies that lines should be solid. »
  • AbsoluteDashing can be used in both two- and three-dimensional graphics, as well as in Style specifications.
  • The following symbolic forms for d can be used: Tiny, Small, Medium, and Large. »
  • If a segment has a length di specified as 0, it is drawn as a dot whose diameter is the thickness of the line.
  • offset is specified in printer's points, and it may be positive or negative. If offset is not specified, it is 0.
  • capform can take any of the legal form values in CapForm[form]. If not specified, all segments will be drawn with the "Butt" cap form.

Basic Examples  (3)

Specify the dashing of lines as successive segments with lengths in printer's points:

Use Dashed, Dotted, and DotDashed to specify predefined absolute dashings:

Scope  (4)

Dashing Specifications  (4)

No dashing:

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

Symbolic values for predefined absolute dashings:

Specify offset to dashed segments:

Specify caps to dashed segments:

Properties & Relations  (3)

AbsoluteDashing defines the length of a segment in units of printer's points:

AbsoluteDashing is independent of the image size:

Dashing defines the length of a segment as a fraction of the total width of the graphic:

Dashing depends on the image size:

AbsoluteDashing overrides the CapForm directive:

Specify the third argument to Dashing to set a cap form for all dashes:

Possible Issues  (1)

Line caps add to the length of individual dashes and may cause closely spaced dashes to overlap:

Vary the offset for dashed rays out of the origin:
