plot3: Time for one periodic orbit

If have x,y,z values as that form a periodic orbit (circle shape) when plotted is it possible to calculate the time it takes for that 1 orbit.

Data(1,:); %x values
Data(2,:);  %y values
Data(3,:);  %z values

%Use plot3 to plot x,y,z values and we get a the first left picture 

plot3(Data(1,:),Data(2,:),Data(3,:))

Is it possible to calculate the time it takes for that 1 period i,e the periodic orbits smallest period.

I looked her but couldn't find anything. Any help or suggestions would be really appreciated.

How to calculate the time? Where is speed/velocity?
