在Gnuplot 4.0中选择线型和颜色

问题描述

我有两对数据集，需要使用Gnuplot进行绘制.

I have two pairs of datasets, which I need to plot using Gnuplot.

我希望将第一对绘制成红色，一个实线，一个虚线.第二对，我想用蓝色绘制，一个实线和一个虚线.

I want the first pair to be plotted in red, one solid and one dashed. The second pair, I want to plot in blue, one solid and one dashed.

我已经尝试过多次set style line，但是我无法获得确切的行为.我的最后一次尝试(随附)将第一对绘制为红色(实线)，将第二对绘制为蓝色(虚线).

I've experimented with set style line several times, but I cannot get this exact behaviour. My last attempt (attached) plots the first pair in red (solid) and the second pair in blue (dotted).

任何帮助将不胜感激.

set style line 1 lt 1 lw 3 pt 3
set style line 2 lt 1 lw 3 pt 3
set style line 3 lt 3 lw 3 pt 3
set style line 4 lt 3 lw 3 pt 3
plot 'data1.dat' using 1:3 w l ls 1,\
     'data1.dat' using 1:4 w l ls 2,\
     'data2.dat' using 1:3 w l ls 3,\
     'data2.dat' using 1:4 w l ls 4

推荐答案

您需要使用 linecolor 而不是lc，例如:

You need to use linecolor instead of lc, like:

set style line 1 lt 1 lw 3 pt 3 linecolor rgb "red"
