If you're working in Python, you should consider matplotlib [1], which 
has a GTK3 backend [2].  If you're not working in Python, you may still 
wish to see if you can wedge matplotlib into your system.  It's rather 
powerful.

As another possibility, you may wish to consider using a WebView and 
one of the many javascript plotting libraries out there.  I'm aware of 
D3 and Bokeh off-hand, though I'm sure there are others.
