hello,

i have a set three data vectors :

x=(datax)

y=(datay)

z=(dataz)

plotting the vectors with plot3d derives the green line displayed in the attached picture.

I want to connect the the point with a smooth curve (on axis z), not a surface,is there a way to do that ?

curve fitting did work fo me.

Thanks in advance

Is your question why curve fitting didn't work? We cannot know without seeing your steps, and how you evaluated the result.

Data=[x(:).';y(:).';z(:).'];
w=width(Data);
XYZ=num2cell(spline(1:w,Data,linspace(1,w,10*w)),2);
plot3(XYZ{:});
