Hi, I would like to plot the following data as a 3D plot (showing just the first column), where 1st column is X, 2nd is Y and 3rd is Z. Does anybody know how would I do that?

0.66455 -0.03190 14.50000

Thanks

Tarsis

For your data, I would use the scatter3 function. If you want to do a surface fit, see the documentation for Scattered Data Interpolation.

My pleasure!

For scatter3, you define them exactly that way:

scatter3(X, Y, Z)

See the documentation for scatter3 (that I provided a link to in my original Answer) for details. You can change the marker type and other options.

If you want a bit more relevant 3D representation (still discrete data and not a surface), you can also use the stem3 function. You would call it the same way:

stem3(X, Y, Z)
