问题描述
我试图在gnuplot中以垂直堆叠的方式绘制5个图.有许多水平(共享x轴)图.我试图调整他们的解决方案.但不知何故.这是代码.
I am trying to plot 5 graph in vertically stacked pattern in gnuplot. There are many horizontally (x axis shared) graphs. I tried to adapt their solution. But somehow not works. Here is code.
set key bottom center

set bmargin DX; set tmargin DX; set lmargin DY; set rmargin DY

unset multiplot
其中四个给出下面的图.代码必须生成5个图形.生成的图像
Which gives below 4 graph in one. Code must generate 5 graph.Generated image
原始图片如下.我想删除图表之间的空白.原始图片
Original image is below. I want to remove blank space between graphs.Original image
推荐答案
Gnuplot空间不足.您需要修复set size和set origin命令，以免在绘制区域之外进行绘制.现在，您的SX=0.25表示每个子图的水平尺寸占用了可用空间的25％，因此只有4个子图可以使用此设置.然后需要将第五个子图放置在绘图区域之外.
Gnuplot is running out of space. You need to fix your set size and set origin commands so that you don't plot outside of the plotting area. Right now, your SX=0.25 means that the horizontal dimension of each subplot takes 25% of the available space, thus only 4 subplots can fit with this setting. The fifth subplot is then required to be placed beyond the plotting area.
还请注意，通过设置原点和尺寸，您将覆盖定义的multiplot layout.
Note also that by setting the origin and the size you're overriding your defined multiplot layout.
通常，在进行这种打印样式时，定义边距而不是大小和原点可能是一个更好的主意.
Usually, when doing this kind of plotting style, it might be a better idea to define the margins rather than the size and origin.
