从数据到在网格上创建/放置圆圈/圆球的简单数据可视化
我想要的只是在网格上为具有不同颜色的特定数据集创建圆圈(根据数据)。这些可能是我创建的放置在网格上或来自程序本身的对象。我正在使用 POVRAY,但它非常复杂,而且我没有时间。除非有人有关于如何从文件中读取数据并提取所有数字并在 .pov 文件中成功使用的教程。
all I want is to create circles (from data) on a grid for specific sets of data with different colours. These might be objects I have created to be placed on grid or from the program itself. I was using POVRAY but it is massively complicated and I don't have the time. Unless anyone has a tutorial on how to read data from files and extract all the numbers and used successfully in .pov files.

有几个程序/环境(非 C++)可以直接执行此操作。一种是 gnuplot;另一个更强大的工具是R。尽管使用 R 需要更多的学习曲线才能真正上手。
There are several programs/environments (not C++) that can do this directly. One is gnuplot; another, more robust tool is R. Although with R there is a bit more of a learning curve to really get moving.
您考虑过 GNUplot 吗?
它具有简单的语法,因此您只需将数据文件转换为 gnuplot 的输入文件即可。
Have you considered GNUplot?
It has a simple syntax, so you can just convert your data file into an input file for gnuplot.
