Hi Xavier,
The Hinton diagram looks fairly close to an image plot, or the
color2D.matplot function. The difference is that the area of the squares
in the Hinton plot are proportional to some value rather than the color,
which indicates the sign of the value. If you have no luck finding this,
I think I could easily morph color2D.matplot into a Hinton diagram
function.
