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. // T On Monday, July 21, 2014 11:09:31 PM UTC+2, Zahirul ALAM wrote: > > Thanks Stefan.
