Hi, I am a newbie for 3D plot. I have a dataset including 1000 rows and 3 columns. I treat each row as one observation, which has three values(three columns). I want to draw a 3D plot using this dataset. I tried to draw it in different ways. I used plot3 and it only gives me lines. I used surf(x,y,z) and mesh(x,y,z) where x, y and z are 1000 by 1 vector only to get error message. Please help me with this. I want to get some kind of smooth surface if possible. Thanks.

You could interpolate to a regular grid and then mesh.

Use TriScatteredInterp or the newer GriddedInterpolant
