linedetails attribute type

lines

DESCRIPTION

A linedetails attribute type controls details regarding the presentation of line(s), including the line color, width, dash pattern, and the scaling of the dashpattern. These details have defaults that will often be satisfactory; text details specifications may be used when it is desired to override the defaults.

Virtually every ploticus attribute comprised of lines has an accompanying linedetails attribute.

A linedetails attribute occupies one line in the script file, and contains one or more sub-attribute settings. A sub-attribute setting has the form subattribute=value with no embedded spaces. Multiple sub-attribute settings on the line are separated by white-space.

SUB-ATTRIBUTES

color= color

: specifies the color of the line.

width=w

: specifies the line width. w is a number between 0.1 (very thin line) to 10 or so (fat line). A typical default value is 1.0.

style=n where n is an integer 0 - 9 that controls the dash pattern of the line:

    0 = solid line   1 = _ _ _ _ _  2 = __ __ __ __  3 = ___ ___ ___
    4 = _._._._._   5 = __.__.__.  6 = ___.___.___  7 = _.._.._.._..
    8 = __..__..__  9 = ___..___..__.

dashscale=z

: controls scaling of the dash pattern. 1.0 is the default, 2.0 doubles the length of the segments, 3.0 triples it, etc.

In addition, no or none may be given as the linedetails to completely suppress the line in question; likewise yes indicates that the line be generated using all of the default detail values.
