DPlot

Thanks. I dont need a tripartite plot but i'm not sure the define boundary gets me what I need (unless I haven't worked it right). I have an example plot but how do I add it to the message?[/img]

Is it possible to create a colour contoured tri-plot? I can create a tri-plot with scatter data or a coloured contoured xyz surface plot but what I need is a combination of those two plots.
