Gnuplot 通过使用multiplot以相同的长度允许每个绘图的X比例以列方式对齐图形
我试图按列顺序绘制五个图（a、b、c、d、e），如下所示 每个图的x标度不同，它们不在垂直线上，但图（c）、（d）和（e）的x范围值几乎相似，即24.8 当我按列顺序绘制这些图时，我发现标记为（a）和（b）的图分别被拉伸和压缩。 然而，标有（c）、（d）和（e）的图具有相同的标度长度 我在垂直方向上画了一条红线，以显示每个图形的x比例是如何对齐的。（请参见附图） 下面给出了我使用的gnuplot脚本Gnuplot 通过使用multiplot以相同的长度允许每个绘图的X比例以列方式对齐图形,gnuplot,Gnuplot,我试图按列顺序绘制五个图（a、b、c、d、e），如下所示 每个图的x标度不同，它们不在垂直线上，但图（c）、（d）和（e）的x范围值几乎相似，即24.8 当我按列顺序绘制这些图时，我发现标记为（a）和（b）的图分别被拉伸和压缩。 然而，标有（c）、（d）和（e）的图具有相同的标度长度 我在垂直方向上画了一条红线，以显示每个图形的x比例是如何对齐的。（请参见附图） 下面给出了我使用的gnuplot脚本 #!/usr/bin/env gnuplot ######################

将xrange[-26.2:26.2]基本上，您必须调整绘图大小和原点的x值，以便最宽的绘图保持其当前大小，而所有其他绘图则根据其较小的范围进行移动和压缩 由于我没有任何数据文件，也无法测试整个脚本，下面是您需要执行的操作的示意图：
xsize(width) = 0.80 * width / width_max
ysize = 0.22
width_max = (2 * 26.2)
