如何在gnuplot中绘制带有彩色边框的矩形 [英] How to draw a rectangle with a colored border in gnuplot

问题描述

我想在绘图中画一个空的矩形.

I would like to draw an empty rectangle in my plot.

到目前为止，我有:

set style rect back fs empty border lt 3 
set object 1 rect from 1,1 to 2,2 

我有一个带有虚线的矩形.如何更改线条的颜色? lc似乎在边界后不起作用.我也尝试设置新的线型和边框，但没有成功.

And I have my rectangle with a dashed line. How do I change the color of the line? lc does not seem to work after border. I also tried with setting a new line style, and border but I was not successful.

谢谢！

推荐答案

在您发布的代码中使用lc代替lt可以在4.6.5版中正常使用

Using lc instead of lt in the code you posted works fine with version 4.6.5:

reset
set style rect back fs empty border lc rgb '#008800'
set object 1 rect from 1,1 to 2,2 lw 5
set object 2 rect from 1,3 to 2,4 lw 5 fs empty border lc rgb '#880088'
plot x

在任何情况下(同时包含lt 3和lc ...)，矩形边框都是实心的.我尝试了wxt，pngcairo，pdfcairo和postscript端子，并每次都设置dashed选项.

In any case (both with lt 3 and lc ...) the rectangle borders are solid. I tried the wxt, pngcairo, pdfcairo and postscript terminals and set the dashed option every time.
