linedetails


Version 2.41 Mar2009


Manual page for linedetails(PL)

Virtually every ploticus attribute that produces lines has an accompanying linedetails specification for controlling line appearance details such as color and thickness.


Examples

Prefab example: linedet2="color=green width=0.5"
Script example: frame: color=green width=3 style=3 dashscale=4.5

Note that settings are separated from each other by space, but settings themselves contain no embedded whitespace. Also, the entire specification must be on one line.


Settings

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

specifies the dashing style. 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.


Suppressing the line

A linedetails specification of no or none may often be given to completely suppress the line in question; likewise yes often may be used to indicate that the line use all of the default detail settings.
