Gnuplot线型 [英] Gnuplot line types

问题描述

如何在gnuplot上绘制不同类型的线?我得画不同的颜色.我的脚本连接了几个文件，我认为这就是为什么行没有破折号的原因.四个中只有两个是虚线. 谢谢 费利佩

How do I draw different types of lines on gnuplot? I got to draw different colors. My script joins several files and I think it is why the lines are not dash. Only two of four are dashed. Thanks Felipe

推荐答案

直到4.6版

linestyle的破折号类型由linetype给出，除非您用linecolor明确设置了另一个颜色，否则它也会选择线条颜色.

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

但是，对虚线的支持取决于所选的终端:

However, the support for dashed lines depends on the selected terminal:

1. 某些终端不支持虚线，例如png(使用libgd)
2. 其他终端(例如pngcairo)支持虚线，但默认情况下处于禁用状态.要启用它，请使用set termoption dashed或set terminal pngcairo dashed ....
3. 端子之间的精确破折号样式有所不同.要查看已定义的linetype，请使用test命令:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

运行

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

给予:

而postscript终端显示不同的破折号:

whereas, the postscript terminal shows different dash patterns:

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

从5.0版开始，引入了与线型，虚线图案和线条颜色相关的以下更改:

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• 引入了新的dashtype参数:

要获取预定义的破折号模式，请使用例如

To get the predefined dash patterns, use e.g.

plot x dashtype 2

您还可以指定自定义破折号图案，例如

You can also specify custom dash patterns like

plot x dashtype (3,5,10,5),\
     2*x dashtype '.-_'

端子选项dashed和solid被忽略.默认情况下，所有行均为实线.要将其更改为虚线，请使用例如

The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

set for [i=1:8] linetype i dashtype i

线色的默认设置已更改.您可以使用set colorsequence default|podo|classic在三种不同的颜色集之间进行选择:

The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:
