This graph is the energy spectrum of wavelet scattering coefficients. How can I draw this graph? How should the energy spectrum of an image be calculated? thank you.

What are your given parameter values and equation?
You can use similar approach as shown in this example:
[x,y]=meshgrid(linspace(0,2*pi));
R = 5;
X = R*cos(x).*sin(y);
Y = R*sin(x).*sin(y);
Z = -R*cos(y);
surf(X,Y,Z)
colormap jet
axis on; shg
view([180 90])
