Simple XY line plot using GtkAda

Simple XY line plot using GtkAda

[ahlan]

Can anyone advise me what I should use to draw a simple line plot using GtkAda (primarily under windows).
Gtk.Extra.Plot seems to have been abandoned and apparently doesn't work on Gtk3 so what should I use? Gtkdatabox also seems to be a relic of history.

Advice gratefully received,
Ahlan

Dear Dmitry,
I thought that using your oscilloscope widget might be a little over the top when all I want to do is plot a few 2D line plots.
But if that is what is recommended I will try it out.
Many thanks,
Ahlan

That is why we need a graphics package as part of Ada standard.

C++ seems to have got the idea of how important this to have
as part of the language, so it is there all the time:

Well, GTK is notorious for killing features. Ada is much less so, in 
that sense, yes.

Vector graphics especially as limited as described in the document is of 
minor interest compared to proper 2D graphics: UI windows, widgets, 
controls. So if you want to start begin with the latter. (:-))

P.S. Many embedded platforms would rather use raster graphics instead of 
the vector one, for obvious reasons. ARM rendering performance is just 
horrific, literally.

There was a thread on plplot package (https://groups.google.com/forum/#!searchin/comp.lang.ada/plplot|sort:date/comp.lang.ada/afb8KEof7Ek/yi7ULXZC5i8J)

It was looking promising, but I never managed to compile it under Windows (frankly, I abandoned it after couple of hours of unsuccessful efforts).

So, I ended up writing text input files for gnuplot from an Ada program. This way I have access to all gnuplot facilities, which are ample.
