[Gnuplot-info] about 4d-plots

[Carsten B. <car...@gm...>]

Dear Gnuplot Developer Team,

I don't want to make this long.

I am using your software since 8 years irregularly when I need it. Just today 
I wrote a small german Introduction (http://www.deshalbfrei.org/
software:gnuplot) and I had a small impression of what I would really like to 
see.


You already have the splot function, using 2 variables.

Could you implement an additional 'qplot' with 3 variables, which paints the 
4. dimension as a grayshade? 

I know there are a lot of perspective problems, as it would be needed to 
rotate it and splice it into several layers to have the overall impression of 
the function, but I think it would be a great idea to visualise the fourth 
orthogonal dimension.

(you could splice it up into n terminal windows or something)

Just an idea.

With best regards,
	Carsten Busse
