我尝试在gnuplot中使用multiplot选项绘制几个图。我使用如下所示的脚本。

#!/usr/bin/env gnuplot


#OUTPUT
#PNG
set terminal pngcairo size 600,550 enhanced dash #font "Arial-Bold,13" #fontscale 1.20
set output "Fill-Multi-plot-LDP-lyoSystemLast50ns.png"

使用此代码我得到如此处所示的图。 multiplot with shaded regions

我在这里遇到的问题是图中标有(a)的情节。蓝色色调必须向下。但它会向上发展。其他数字(b),(c)等是正确的。

图标签(a)的相应代码在代码中的#(PLOT E)#部分给出。特别是蓝色阴影的线条如下:(u 1:4 w fillcurves fs透明固体0.5 ls 6)

我无法弄清楚我在这里犯的错误或错误是什么。

(注意:代码和相应数字的顺序是颠倒的)。

我感谢任何纠正此代码的帮助。非常感谢提前。

您想要填充曲线和下X轴之间的区域。这是通过选项x1

完成的
plot 'file.dat' with filledcurves x1 fs transparent solid 0.5 ls 6

我认为您可以为所有区域设置x1
