Did you try something? Your desire is not enough. I want some effort

Something like this

data = readmatrix('final.xlsx');

x = data(:,1);
y = data(:,2);
v = data(:,3);

[X,Y] = meshgrid(unique(x), unique(y));
V = reshape(v, size(X));

contour(X,Y,V);

Data values at a few points are messing up the colors of all the contour lines. You mat consider filtering values in matrix v in the above code.
