Generic Mapping Tools

[Ismael Núñez-Riboni]

Anybody combining Octave (3.4.3) with the generic mapping tools of the 
Hawaii University (http://gmt.soest.hawaii.edu/)?

I already googled, I'm aware of the MEX files to read grid files under 
Octave, but I wonder if there is an easy way of plotting from Octave 
using the GMT as a backend, i.e., not necessarily dreaming of this:

graphics_toolkit gmt

but at least some functions in Octave that pass data to be plotted as 
arguments to the GMT functions (not by saving on disk) to plot the data 
using GMT (and ideally in a X11 window and not to a PS file).

Thanks a lot for the answer in advance... Cheers, Ismael.
