Gnuplot: single point in 3D with variable's as coordinates

Question

I plotted some equations in 3D mode with parametric and calculated their extremal points. This way I got xPos, yPos and zPos as coords.

How do I plot this point in addition to my other graphs? (latest Gnuplot 4.6.5)

I found this article, but this handles only static typed coords and Gnuplot crashes when using with splot + xyz.

I think the easiest way to place a single point at given coordinates is to place an empty label with a point at that position:

set label at xPos, yPos, zPos "" point pt 7
splot ...

With sprintf( "min(%.1f|%.1f|%.1f)" , xPos , yPos , zPos ) as title ~> awesome
