How I can draw 3D for the data below to have as in tha attached photo
X = [65 70 75 80 85 90 95 100];
Y = [36 38 40 42 44 46 50 54];
Z = [1792.373894 1178.621038 685.7078009 416.4883705 365.9043439 450.2110549 700.8830089 1040.358032];

Whay you get is this:
X = [65 70 75 80 85 90 95 100];
Y = [36 38 40 42 44 46 50 54];
Z = [1792.373894 1178.621038 685.7078009 416.4883705 365.9043439 450.2110549 700.8830089 1040.358032];
m = numel(X) ;
Z = repmat(Z,m,1) ;
surf(X,Y,Z)

Try something like this
X = [65 70 75 80 85 90 95 100];
Y = [36 38 40 42 44 46 50 54];
Z = [1792.373894 1178.621038 685.7078009 416.4883705 365.9043439 450.2110549 700.8830089 1040.358032];
xv = linspace(min(X), max(X), 100);
yv = linspace(min(Y), max(Y), 100);
[xg, yg] = meshgrid(xv, yv);
zg = griddata(X, Y, Z, xg, yg);
mesh(xg, yg, zg);
