I was going to this issue when pointing the use of GArray for the data 
and add a *_push_point(x,y) method in the graph object. We can use the 
GArray functionality for growing arrays of points and take the lenght 
and other data at drawing time, not at creation time. Sounds reasonable? 
(Maybe add a configurable maximum length or sth)
