"Add_Plot" doesn't exist anymore in recent version of GtkAda.
I've done a small patch against win_io_3.0_src to make it compile with 
GtkAda-gpl-2.10.2. I've done a light test and it's look like OK
no warranty of course.
copy the rest of the message in a file as "add_plot.patch" inside 
win_io_3.0_src then run patch -p0 <add_plot.patch
