GTK3 + gnuplot

[arkkimede <arkkimede gmail com>]

Hi!
I've developed an application in c to make measurements, with a GUI that
manage the inputs and it is able to produce graphical results in terms of
2d plots, realized by mean of the library Cairo.

Now I have the necessity to produce 3d plots (3d radiation pattern of
antennas).

To realize 3d plots by mean of a 2d library, is not impossible but very
hard.
A solution could be using gnuplot that I'he yet used to produce high
quality 3d plots.

The question now is: "How to embed a gnuplot graphic in gtk3?
Could you say, please, where to find a simple example, just to undestand
how it is possible to do that?

Thank you
