There is, actually, some functionality for contour and density plot 
already, but all the nuts and bolts aren't really tightened yet, and I 
don't know if the progress so far has been documented at all, but if you 
have a function `f = (x,y) -> z(x,y)`, you can do `plot(f, xmin, xmax, 
ymin, ymax)` to get a nice contour plot. Support for contour plots of 
matrices is under construction - take a look at 
[#293](https://github.com/dcjones/Gadfly.jl/issues/293) for more details.

Density plots is sort-of implemented through 
[Geom.rectbin](http://dcjones.github.io/Gadfly.jl/geom_rectbin.html) which 
may or may not be what you need.
