Dashing

Dashing[{r1,r2,…}]

is a two-dimensional graphics directive specifying that lines that follow are to be drawn dashed, with successive segments of lengths r1, r2, … (repeated cyclically). The ri are given as a fraction of the total width of the graph.

Dashing[r]

is equivalent to Dashing[{r,r}].

Details

  • Dashing can be used in both two- and three-dimensional graphics, as well as in Style specifications.
  • Dashing[{}] specifies that lines should be solid. »
  • The following symbolic forms for r can be used: Tiny, Small, Medium, and Large. These specify absolute segment lengths independent of the total width of the graphic. »
  • If a segment has a length ri specified as 0, it is drawn as a dot whose diameter is the thickness of the line. »

Properties & Relations  (5)

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

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

Dashing depends on the image size:

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

AbsoluteDashing is independent of the image size:

The thickness of segments can be specified by Thickness:

A segment with length 0 specifies a dot of the size defined by Thickness:
