I have a matrix that contains magnetic data in 3 axis (x,y,z) along with time (4th column). I need to plot this in a 3D graph, not points but lines of diffeernt color or some kind of mesh/net structure. How can i do that?

T = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1392204/plotdata.xlsx') ;
Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

x = T.(3) ;
y = T.(4) ;
z = T.(5) ;
dx = gradient(x) ;
dy = gradient(y) ;
dz = gradient(z) ;

In the above plot, the time data is missing. Can we represent it all in one plot?
