如何在飞机上有效地分配点(How to effectively distribute points on plane)

 我认为我应该回应我自己的问题，至少这是一个结案。 
 
 经过一些更深入的挖掘，并从我收到的评论中，最终结果是gnuplot postscript终端不处理透明度，而pdf和pdfcairo终端则处理透明度。 
 
 诀窍是使用pdftops从.pdf生成一个.eps文件： 
 
#!/bin/bash

gnuplot << GNU

set term pdf
set out "out.pdf"

plot "<jot -r -p 2 500 1 2" not w p pt 7 ps 4 lc rgb "#908DB6CD"

GNU

pdftops -eps out.pdf
 
 生成的所有.eps文件都将被合并到LaTeX文档中。 然后，我可以切换到PDFLaTeX并结束它。 但是，有时我喜欢编辑.eps来手动或使用awk / sed来调整边界框和其他东西。 无论如何，希望这是有帮助的。 

I think I should respond to my own question, so at least this becomes a case closed.
 
After some more digging, and from the comments I received, the bottom line is that the gnuplot postscript terminal does not handle transparency, while the pdf and pdfcairo terminals do.
 
The trick is to generate an .eps file from a .pdf using pdftops:
 
#!/bin/bash

gnuplot << GNU

set term pdf
set out "out.pdf"

plot "<jot -r -p 2 500 1 2" not w p pt 7 ps 4 lc rgb "#908DB6CD"

GNU

pdftops -eps out.pdf
 
All of my .eps files are generated to be incorporated to LaTeX documents. Then, I could just switch to PDFLaTeX and be over with it. However, at times I like to edit the .eps to tweak the bounding box and other things by hand or using awk/sed. Anyway, hope this is helpful.
