contour plotting without interpolation

Hi,

I am wondering if it is possible to perform a contour plot without any data interpolation being applied. I have x,y,z data that I would like to plot as: contour, filled contour, and 3d contour without any interpolation of the z data being applied.

I am aware that a roundabout method will need to be used to achieve this, as the low level contourc method has no option to mess with the interpolating mechanism, so I am wondering if anyone has already been down this path. Contour plotting has the very nice property of allowing me to select the levels at which separate contour levels are generated, but the smoothing applied to make the graphs look pretty is destroying details in my data.

Essentially what I need is a surface plot for which I can disable face coloring and only have colored lines appear at the 'contour level' transition points.

There must be a way to do this. Please help!

Thanks,
Will
