Plotting (x,y,z) style data

I have a set of data (z) which is dependant on two variables (x and y). x and y are not linearly spaced, for instance the values for x are 1,5,15,20,25,30 and the values of y are 2.8265, 6.0901, 8.4037, 9.7438, 15.4105, 16.2210, 18.0747, 27.0028, 32.9710, 33.4117, 36.8778, 47.0123, 47.1012, 64.0642, 64.8562, 66.9691, 70.2852, 85.6802, 89.2302, 93.1160 I've currently got the data in the form of a list of triples i.e. { {x1,y1,z1},{x2,y2,z2} .....} I'm trying to fit a model to this data, and as part of that I'd like to plot it. What's the best way of plotting this type of 3D data in Mathematica (note: I'm a bit of a Mathematica novice). By the way, the spacing of the independant variables is a feature of the experiment the data comes from and not a lot can be done about it. Also, I'd love to post the actual data (as it's not proving particularly easy to fit a model to it) but I pretty sure that my boss would regard the data as commercially sensitive and forbid me to do so. Sorry. TIA --Emma emma.gottesman at snellwilcox.com
