Yes, I knew about PlPlot ofcourse, thanks, and looked at it as well as
manyothers.

I wanted ONE library to do both GUI building (i.e. make canvas,
layout button, graphics area, sliders, pop-up menus, etc... on it)
and also do data visualization (plotting 2d, 3d, mesh plots, etc...),
like I can do now easily with Matlab and Mathematica for example.

I did not see that I can build a GUI with plplot? But I saw I
can build a gui with gtk+ but no do plotting.

you say plplot works with gtk+, I am not sure what that means. do you
have examples, screen shots of apps written in gtk+ as GUI using
plplots into a drawing area created by gtk+? I thought it will be
easier to learn one library that 2.

What I am looking for, is there a way in Ada to make a gui, say such
as this example: (this is just a random one I picked on the net,
it uses Matlab GUI and plotting):

http://lims.mech.northwestern.edu/projects/frictioninducedforcefields/index.htm

Now, given all the above, for scientific applications, I still
need to be able to access lapack functions from Ada. Ada Annex G
just does not cut it. Very limited. As well as what other small
Ada math libraries I could find.


So far, I could not find full binding to these. There are 100's of
functions there, that has been written over span of more than 30
years or more:

http://www.netlib.org/lapack/release_notes.html

that one would need to call to do any type of scientific
work. Without being able to uses these from Ada, having the
GUI and the plotting will do me no good. I need to have all
the 3 parts (GUI + Plotting + Lapack binding) as a starting
point to even think about using Ada for numerical work.
