How do you do a color contour plot (map view) with interpolation between values from a data set when the values don't follow a consistent matrix?  The x axis is time (a date), the y axis is water depth (e.g., 0-20 meters), and the z value is water temperature (0-30C).

The data is scattered enough that it cannot be put into a matrix usable by pm3d (AFAIK).  This is because the time values are not always consistently spaced and may have large gaps in them and there are some missing values here and there for water temperatures at various depths.

Thanks much for any insight you can provide!
