我有一个看起来不漂亮的多余情节，这应该是一篇物理论文。虽然我可以看到很多问题，但最令人沮丧的是，似乎Gnuplot完全违反了我在某些子图上设置的ytics命令。此外，第一个绘图的轴标签最终会在第二个绘图上结束。我如何解决这些Gnuplot有自己的想法并拒绝做我说的问题？

答案 0 :(得分：0)
ytic设置仅在放置在plot命令之前才有效。这适用于所有设置。必须在相应的plot命令之前完成必须出现在图表和所有设置中的所有内容：
set ytics 1
plot x
以下是您脚本的改进版本：

set style data lines

unset multiplot
要点是：
set multiplot layout 4,2自动更改尺寸和原点。xlabel和ylabel。 set ytics。ytics的开始和结束，而只能指定增量。graph 0.01,0.9）。并始终使用相同的标签ID（1）。然后对于第二个和所有后续图表，您必须仅更改文本，使用旧坐标。然后，您只需在代码中的一个位置微调标签位置。set style data lines unset key隐藏图例。
