Plot 2-d contour of 3D dataset

I have a dataset with the following collumns: x, y, z, V. Rows are points V(x,y,z).

I wish to plot contours in the XY plane with the V values.

I have done:

[X,Y] = meshgrid(x,y)

how do I lay V data across the meshgrid so I can plot contour(X,Y,V)?

[Akira Agata]

How about using scatteredInterpolant function to calculate V values for each meshgrid point?

Read about slice. Else attach your data.

The data attached is structured as follows:

column1 : x - coordinates in meters

column2 : y - coordinates in meters

column3 : z - coordinates in meters

column4 : Intensity at x, y, z in arbitrary units

Thank you

How about this?

T = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1099910/data_16082022.csv') ;
x = T.(1) ;
y = T.(2) ;
z = T.(3) ;
v = T.(4) ; 

dt = delaunayTriangulation(x,y,z) ;
patch('faces',dt.ConnectivityList,'vertices',dt.Points,'facevertexcdata',v,'facecolor','interp','edgecolor','none') ;
