I have posted the first version of Scattergram plugin (requires QGis 1.0 
and Qwt5).
The calculation is reasonably fast although it uses 
QpsRasterLayer::identify to retrieve the values. Retrieving 1 million 
values takes about 5-10 seconds. The interface is not frozen because the 
retrieval is done step by step using a QTimer based threading-like approach.

See also ValueTool posted about one week ago.
