Plotting library for GTK+

["Sergei Naumov" <vomus rambler ru>]

Hi, folks!

I think this question was asked many times but googling gives a rather patchy
answer to it. So, I am writing a piece of C code that acquires some data from
hardware controllers and it also has to plot a few simple graphs and histograms
out of them. What is a "canonical" tool for such a purpose?

I played a bit with GtkExtra but it seems that the project is somewhat forgotten
and it does not have all the documentation in it. I also looked at Cairo but it
is a low level library so I would have to implement all the scaling, axes, ticks
and stuff myself. There are some interactive tools based on GTK but I need a
library, as I have to build in plotting functionality.

Can anyone help?
