Gnuplot：从文件 .plt 插入
Gnuplot: inset from file .plt
我有 2 个通用 Gnuplot 文件：plot1.plt 和 plot2.plt 已经保存。
我需要将它们合并到一个图中，其中 plot2.plt 是 plot1.plt.
的插图
我想我可以用图片解释得更好。
最后的结果，比方说，应该是这样的
在这张图片中 plot2.plt 是插图，主要情节是 plot1.plt。每个文件都可以正确独立地加载到Gnuplot中。
感谢您的任何建议。
编辑：
代码（但它不能正常工作）是这样的：
set multiplot
load "plot1.plt" # plot main figure
set size 0.6, 0.5 # set size of inset
set origin 0.4, 0.5 # move bottom left corner of inset
load "plot2.plt" # plot inset
unset multiplot
plot1.plt 和 plot2.plt 是通用绘图文件。为了不让它变得更复杂，您可以通过这种方式生成它们：
plot sin(x)
save "plot1.plt" #or choose your folder
plot exp(x)
save "plot2.plt" #or choose your folder
以上代码产生：
What I get from the code above
不幸的是，为插图设置不同的大小或原点不会影响结果。
我正在使用 GNUPLOT 版本 5.0 补丁级别 4。

我现在提供文件 plot1.plt 的代码。如果您认为它太长，请随时编辑和删除（全部或部分）它。

没有您的代码，必须就此打住，但这应该能让您继续。
好的，
我自己找到了答案，所以我要分享我的发现。
在问题中，让 plot2.plt 成为 plot1.plt 的插入。使用任何文本编辑器打开 plot2.plt 我们可以看到情节背后的代码。我们必须搜索这两行：
set size ratio 0 1,1
set origin 0,0
因为 plot2.plt 在我的示例中是在命令 set size 和 set origin、
之后加载的
set multiplot
load "plot1.plt" # plot main figure
set size 0.6, 0.5 # set size of inset
set origin 0.4, 0.5 # move bottom left corner of inset
load "plot2.plt" # plot inset
unset multiplot
它们覆盖了预期的正确尺寸和比例。为了解决这个问题，我以这种方式结束了对 plot2.plt 的编辑：
set size ratio 0 0.6,0.5 #old line: set size ratio 0 1,1
set origin 0.4,0.5 #old line: set origin 0,0
假设我们将修改后的文件保存为 plot2_mod.plt。现在，为了获得正确的插图，我们可以这样写：
set multiplot
load "plot1.plt" # plot main figure
load "plot2_mod.plt" # plot inset
unset multiplot
结果是：
Plot with the desired inset
显然还有一些工作要做，但这回答了问题的要点：如何使用已保存的 .plt 文件绘制插图。
