在gnuplot中仅使用箭头创建向量 [英] Creating vectors with only the arrowhead in gnuplot

问题描述

一个人如何创建一个没有线条而只有箭头的矢量?

有一个名为"nohead"的选项，它除去了箭头的头部，但我想相反，除去向量的线，只保留头部.

最优选地，还可以基于单个数字重新缩放此箭头的大小.

解决方案

在

How does one create a vector without the line and just the arrowhead?

There is an option called "nohead" which removed the head of the arrow, but I want to do the opposite, remove the line of the vector and only keep the head.

Most preferably also be able to re-scale the size of this arrowhead based on a single number.

解决方案

Found some useful advices on TeXExchange, seems like exactly what you were looking for. The right command that you need is fixed which allows to plot only the head

set style arrow 11 head filled size 7, 20, 60 fixed lt -1 

Otherwise have a look on SourceForge, were you find the originally solved question!

EDIT: The result will look something like this
