如何在 gnuplot 上绘制不同类型的线条?我要画不同的颜色。我的脚本加入了几个文件,我认为这就是为什么这些行不是破折号的原因。四个中只有两个是虚线。谢谢费利佩

#!/usr/bin/gnuplot

set grid

直到版本 4.6

a 的破折号类型由linestyle给出linetype,它也会选择线条颜色,除非您使用 明确设置另一个linecolor

但是,对虚线的支持取决于所选终端:

  1. 某些终端不支持虚线,例如png(uses libgd)
  2. 其他终端,如pngcairo,支持虚线,但默认禁用。要启用它,请使用set termoption dashedset terminal pngcairo dashed ...
  3. 终端之间的确切破折号模式不同。要查看定义的linetype,请使用以下test命令:

跑步

set terminal pngcairo dashed
set output 'test.png'
test
set output

给出:

postscript终端显示不同的破折号模式:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

5.0 版

从 5.0 版开始,引入了以下与线型、虚线图案和线条颜色相关的更改:

  • 引入了一个新dashtype参数:

    要获得预定义的破折号模式,请使用例如

    plot x dashtype 2
    

    您还可以指定自定义破折号模式,例如

    plot x dashtype (3,5,10,5),\
         2*x dashtype '.-_'
    
  • 终端选项dashedsolid被忽略。默认情况下,所有线条都是实心的。要将它们更改为虚线,请使用例如

    set for [i=1:8] linetype i dashtype i
    
  • 更改了默认的线条颜色集。您可以通过以下方式在三种不同的颜色集之间进行选择set colorsequence default|podo|classic
