Plotting a normal plane with rotation

I am currently trying to plot a normal plane without rotating the plane itself. The code should be able to handle any normal vector except when normal=[0 0 0]; As of now, I have managed to generate the normal plane but had no idea how to prevent the plane itself from rotating. The desired outcome is the black color box. I have attached the code below for your references. The plane is supposed to be tilted upwards instead of rotating. Thank you.

%% Starting of code

PlaneOrigin=[1 0 0]; PlaneNormal=[1 1 1];

w = null(PlaneNormal); % Find two orthonormal vectors which are orthogonal to SourcePlaneNormal [P,Q] = meshgrid(-1:1); % Provide a gridwork (you choose the size) X = PlaneOrigin(1)+w(1,1)*P+w(1,2)*Q; % Compute the corresponding cartesian coordinates Y = PlaneOrigin(2)+w(2,1)*P+w(2,2)*Q; % using the two vectors in w Z = PlaneOrigin(3)+w(3,1)*P+w(3,2)*Q; hSurface=surf(X,Y,Z); set(hSurface,'facealpha',1,'edgealpha',1,'FaceColor','green'); axis auto; axis equal;
