如何在gnuplot中设置标签和行相同的颜色 [英] how to set label and line the same color in gnuplot

问题描述

很简单的东西。我想要一个函数，说函数f，用特定的颜色绘制。我还想要一个标签说功能f颜色，也显示在那种颜色。

我试试这个到目前为止：

 设置样式行1 lw 3 lc 1 
在0，70设置标签ACtextcolor 1 
  

但显然lc和textcolor遵循不同的规格，并且抱怨：

 trolo4.pl，第8行：colorspec选项无法识别
  

任何帮助将是伟大的！

解决方案

@holygeek的答案工作正常。来自python，我发现通常更好一些更明确。

 设置样式行1 lw 1 lc rgb red
在0时设置标签AC，70 tc rgbred
  

注意，你的gnuplot识别的颜色名称是系统依赖的（参见 show colornames 一个完整的列表）。要实现完全的系统独立性，可以使用 #RRGGBB 版本。例如红色是'＃ff0000 ，绿色是＃00ff00 ，蓝色是＃0000ff 。当然，你可以组成各种有趣的颜色（再次，请参阅 show colornames 获取预定义颜色及其等效＃的列表。 .... ）

Very simple stuff. I want a function, say function f, to be plotted with a particular color. I also want a piece of label saying "function f color" which is also displayed in that color.

I am trying this so far:

set style line 1 lw 3 lc 1
set label "AC" at 0, 70 textcolor 1

but apparently the "lc" and "textcolor" follows different specs, and it complains:

"trolo4.pl", line 8: colorspec option not recognized

any help would be great!

解决方案

The answer by @holygeek works fine. Coming from python, I find that it is often nice to be a little more explicit.

set style line 1 lw 1 lc rgb "red"
set label "AC" at 0, 70 tc rgb "red"

Note that the set of color names recognized by your gnuplot is system dependent (see show colornames for a complete list). To achieve complete system independence, you can use the #RRGGBB version. e.g. red is '#ff0000, green is #00ff00 and blue is #0000ff. of course, you can make up all sorts of interesting colors (again, see show colornames for a list of pre-defined colors and their equivalent #.....)
