gnuplot map 中出现重影键
[英]Ghosting keys appeared in gnuplot map
问题描述
我想使用gnuplot来plot风向和一个区域，但是map上出现了两个键，我不知道如何解决。 数据量太大，贴不上，不好意思。 [1:97][1:88] 是该区域的域。
set terminal postscript portrait color enhanced 12
set output "wind.ps"
set pm3d corners2color c1 map
set palette defined (0 0 0 1, 0.5 1 1 1, 1 1 0 0)
set multiplot
unset xtics
unset ytics
set lmargin 0
set rmargin 0
set tmargin 0.5
set bmargin 0
set size 1,0.5
set size ratio 0.80745
set origin 0,0.2
set key at 92,13 title "Difference"
set title "(a) Test Wind Field"
splot "wind.txt" u ($1):($2):(1):($3):($4):(1) w vec lt 1 notitle
splot [1:97][1:88] "counrty.txt" u ((($1)-282)/12)+1:((($2)+906)/12)+1:1 notitle w l lt -1 lw 0.5
unset label
如果我将 [1:97][1:88] 添加到 wind 的命令行，重影键会消失，而不需要的行会出现。
splot [1:97][1:88] "wind.txt" u ($1):($2):(1):($3):($4):(1) w vec lt 1 notitle
添加后的风向 [1:97][1:88]
如果我使用命令'plot'来plot风向，那么它会是这样的。
plot "yrd.wind.covid19.txt" u ($1):($2):($3):($4) w vec lt 1 notitle
如果去掉 [1:97][1:88]，它将是下面显示的 map。
splot "counrty.txt" u ((($1)-282)/12)+1:((($2)+906)/12)+1:1 notitle w l lt -1 lw 0.5,\
"yrd.wind.covid19.txt" u ($1):($2):(1):($3):($4):(1) w vec lt 1 notitle
这是风向数据文件。

使用来自gnuplotting.org/的数据和您的风向数据，这个小代码......
reset
set terminal pngcairo size 600,600
set output "world_n_wind.png"
unset tics
set size ratio -1
set xrange [1:97]
set yrange [1:88]
set key at 92,13 title "title key"
set title "title plot"
wind = "wind_direction.txt"
world = "world_50m.txt"
plot \
world u 1:2 w l lt 1 not ,\
wind u 1:2:3:4 w vec lt 2 not
...生成此 plot：
正如@theozh所指出的，您不需要splot而只需要plot命令。
