问题描述

是否有一种简单的方法可以在gnuplot中获得带有黑色轮廓的点?我正在使用标准的颜色填充点类型，例如:

Is there a easy way to get points with black outline in gnuplot? I'm using standard color filled point types, for example:

set style line 3  lc rgb '#4682B4' pt 9 ps 0.65

但我需要确保该图将易于以黑色&白色版本也.黑色轮廓会有所帮助，如何添加它们?

but I need to make sure that the plot will be easily readable in black & white version too. Black outlines would help, how can I add them?

推荐答案

想到的最简单的快速且肮脏的"解决方案是将数据集绘制两次，一次使用完整符号样式，然后使用空符号样式.例如:

The simplest "quick and dirty" solution that comes to mind is to plot the data set twice, once with the full symbol style and then with an empty symbol style. For instance:

plot "temp" pt 9 ps 2, "temp" pt 8 ps 2 lc 0 lw 2
