输出 y 轴展平

Question

我正在尝试重现（第一个答案是 12 个框），但我的输出被粉碎、压平，例如，y 轴都被压平了。这是我在文本文件中的内容，然后在命令行运行 gnuplot

我怎样做才能获得 1:1 比率？

Answer 1

set size ratio 1.0 将强制绘图为正方形。但是它们将是非常小的正方形，除非您采取措施防止标题和 top/bottom 边距占据大部分 space.

要了解其工作原理，请尝试

set tmargin 0
set bmargin 0
set title offset 0,-1
###
... rest of commands as before ...
###

然后您可以决定如何调整标题位置或如何标记各个图，这样就不需要额外的垂直 space。您还可以考虑使用 set multiplot layout 命令的 margins 关键字。

输出 y 轴展平

Output y-axes flattened
