Hi,

I've created a table with variables 'X','Y','Z' where numers represents the spatial coordinates of points taken from CMM measurements. Basically, each row of my table provides the x,y,z coordinates of a point (and I have data for more than 500 points). I'm looking for a way to plot these points in order to recreate a figure (hopefully, as close to a circumference as possible) but I have some problems. I've tried with a simple plot3(X,Y,Z) but basically it returns a sort of mixture of time series.

I don't know exactly how to combine the x,y,z data together to identify a point in the space.

Here an example of a table I've created.

Any suggestion willbe extremely welcomed! :)
