RE: Doubts about gtkplot (from gtkextra)

["MQ" <marcodev comcast net>]

I agree with Al. I have used gtkplot in our proprietary memory debugger.
This tool is now standard inclusion accross all programs in our company and
has been delievered to and requested by our customer, mainly the us military
(navy, air force, etc). They are used to very old fashioned technology when
it comes to data plotting/debugging and they like the new toy. So this tool
has to be very robust. As Al said there have been some bumps along the way
and there is a lot of "figuring" stuff out without the documentation but if
you understand some basic GTK standards (naming, etc) you'll have no
problem. Besides although there is not much traffic on the list it is
monitored by people like Adrian, Al and myself.

I think gtkplot is a great library.

Good luck.
