如何在单个绘图命令的gnuplot命令脚本中嵌入多个数据集? [英] How to embed multiple datasets in a gnuplot command script for a single plot command?

问题描述

我发现在gnuplot中，可以从一个文件中获取多个曲线/数据集:

I found out that in gnuplot one can obtain multiple curves / datasets from a single file:

splot "file.dat" using 1:2:3, splot "file.dat" using 1:4:5

也可以像这样将数据嵌入脚本中:

Also one can embed data in a script like so:

splot "-" using 1:2:3
 1 0 1
 1 2 3
 0.5 3 1.5

但是，以下内容似乎无效:

However, the following seems not to work:

splot "-" using 1:2:3, "-" using 1:4:5
 1 0 1 4 4
 1 2 3 3 4
 0.5 3 1.5 2.5 -1

这是故意的，是否存在解决方法，或者根本不可能吗?

is this intentional, does a workaround exist or is it simply not possible?

推荐答案

以下脚本按预期可与Gnuplot 4.4一起使用.输出附在下面

The following script works with Gnuplot 4.4 as expected. The output attached below

set terminal png
set output 'e.png'
splot "-" using 1:2:3, "" using 1:2:3
 1 0 1 4 4
 1 2 3 3 4
 0.5 3 1.5 2.5 -1
e
 1 4 4
 1 3 4
 0.5 2.5 -1
e
set output

使用1:2:3绘制-"，使用1:2:3绘制-"
