如何在GNUPLOT中制作彩虹盒,gnuplot,Gnuplot,我想用普朗克分布曲线在可见光区域制作一个彩虹填充的盒子。我不知道如何用彩虹填充这个盒子我放了一个盒子 set object 1 rectangle from 3600,0 to 8200,3.6 fs solid 0.4 及是用来上色的。但我唯一能做的就是用一种颜色填充它我看到了一些用于绘图的彩色演示，比如pm3d或一些调色板，但它不会把它们放在带有调色板的obj着色上来自维基，我想要彩虹盒：去年我真的想画出完全相同的图。我找不到一个gnuplot解决方案（我很确定它是存在的…

我想用普朗克分布曲线在可见光区域制作一个彩虹填充的盒子。我不知道如何用彩虹填充这个盒子

我放了一个盒子

set object 1 rectangle from 3600,0 to 8200,3.6 fs solid 0.4

及

是用来上色的。但我唯一能做的就是用一种颜色填充它

我看到了一些用于绘图的彩色演示，比如pm3d或一些调色板，但它不会把它们放在带有调色板的obj着色上

来自维基，我想要彩虹盒：

去年我真的想画出完全相同的图。我找不到一个

gnuplot

解决方案（我很确定它是存在的…），最后我用

awk

部分编写了一个脚本，生成了一个波长范围内带有RGB颜色的文件，然后在

gnuplot

中用

脉冲lc RGB变量

绘制这些文件。我使用了一些问题中的代码，但记不起原始来源。无论如何，请使用下面的代码：
