我有两个来自其中任何一个的文件我将使用以下代码绘制一个点线:
set terminal postscript eps color solid font "Helvetica, 22"
set size ratio 0.625
set output "example.eps"
set key right top
plot "traffic.txt" using 1:2 title "traffic" with lp pt 7 ps 1 lc rgb "red", \
"solar.txt" using 1:($2*100) title "solar" with lp pt 9 ps 1 lc rgb "blue"
任一条线与x轴一起形成区域,并且由两条线形成的区域重叠。我想知道如何遮盖重叠的部分。
谢谢!

您可以使用filledcurves
绘图样式。为此,所有数据必须包含在一个文件中。您可以即时组合文件,例如与paste
。对于具有python外观的平台无关解决方案,例如: this answer
使用filledcurves
,您还可以区分above
和below
以使用不同的颜色:
set key right top
set autoscale xfix
set xtics 4
plot "< paste traffic.txt solar.txt" using 1:2:($4*100) with filledcurves below lc rgb "#ffaaaa" t '', \
"" using 1:2:($4*100) with filledcurves above lc rgb "#aaaaff" t '',\
"traffic.txt" using 1:2 title "traffic" with lp pt 7 ps 1 lc rgb "red", \
"solar.txt" using 1:($2*100) title "solar" with lp pt 9 ps 1 lc rgb "blue"
4.6.4的结果是:
要仅遮蔽两条曲线重叠的区域,您需要一个工作日。首先遮蔽较窄曲线和x1轴之间的区域,然后用白色覆盖该阴影的部分:
set autoscale xfix
set xtics 4
plot "< paste traffic.txt solar.txt" using 1:($4*100) with filledcurves x1 lc rgb "#ffaaaa" t '', \
"" using 1:2:($4*100) with filledcurves below lc rgb "white" t '',\
"traffic.txt" using 1:2 title "traffic" with lp pt 7 ps 1 lc rgb "red", \
"solar.txt" using 1:($2*100) title "solar" with lp pt 9 ps 1 lc rgb "blue"
这给出了:
