我在多画面环境中使用gnuplot。我想只有一个密钥箱（这不是问题），我希望在图表下放入“水平模式”。
Nice Plot1 | Nice Plot2
Nice Plot3 | Nice Plot4
the keybox
似乎密钥箱的总大小不能超过其对应图的宽度（所以这里是屏幕尺寸的一半）。这导致密钥箱中的行返回，我不想要。
无论如何都要绕过它？
感谢。
编辑：添加了脚本。 （密钥箱在3行）

答案 0 :(得分：3)
这是一个丑陋的问题。我从来没有真正使用过epslatex终端 - 这可能会导致额外的复杂情况，因为文档说明了
“当使用Tex终端...格式化信息嵌入字符串时，gnuplot只能估计字符串定位的正确宽度”
你是对的，因为gnuplot似乎不想制作一个比情节宽的键 - 太糟糕了，你不能明确地指定宽度，就像你可以用一个rectangle。这很容易解决。诀窍是使你的情节（没有键）正常，然后制作一个最终的“空”图，它与你需要它一样大，以适应标签：
set term ...
set output ...
#Let the magic begin!
set multiplot
unset key
#<plot 1>
#...
#</plot 1>
#<plot 2>
#...
#</plot 2>
#<plot 3>
#...
#</plot 3>
#<plot 4>
#...
#</plot 4>
#<null>
#here we need to unset everything that was set previously
unset origin
unset border
unset tics
unset label
unset arrow
unset title
unset object
#Now set the size of this plot to something BIG
set size 2,2 #however big you need it
#example key settings
set key box
set key horizontal reverse samplen 1 width -4 maxrows 1 maxcols 12
set key at screen 0.5,screen 0.15 center top
#We need to set an explicit xrange. Anything will work really.
set xrange [-1:1]
set yrange [-1:1]
plot NaN w title 'title 1',\
NaN w title 'title 2',\
NaN w title 'title 3',\
NaN w title 'title 4' #etc.
#</null>
unset multiplot #<--- Necessary for some terminals, but not postscript I don't think.
