How to add contour plot to xz and yz surface to 3d plot

Hello All,

I have a 3d plot created with surfc.

I want to create contour lines on the xz and yz surface of the backround also.

How can i do it? I attached my 3d data.

Thanks for advance.

I am not certain what the desired result is.

Try this —

LD = load('matlab.mat');

figure
surf(LD.x, LD.y, LD.V0)
hold on
contour3(LD.x, LD.y, LD.V0, '-r', 'LineWidth',1)
hold off
grid on
xlabel('x')
ylabel('y')
zlabel('V_0')

.

Hello,

Thanks for answer but i want contours on the walls corresponding to xz and yz planes of the plot.

As given below.

Are the contours I already plotted to be projected onto the ‘Energy’ axis instead of onto the surface itself? That would be relatively straightforward, and would simply be a series of horizontal lines on each axis.

[Özgür Alaydin]

Yes, that is true. Should be projected onto Energy axis.

Problem is solved.

plot3(X*1e9, My/2*ones(size(Y))*1E9, V0*1000, 'LineWidth', 1.5,'color',[0.4 1 0.4]);

plot3(-Mx/2*ones(size(X))*1E9, Y*1e9, V0*1000, 'LineWidth', 1.5,'color',[0.4 1 0.4]);

%%% mesh plotting is also working.

Thanks for help

As always, my pleasure!

(I do not understand the variables referred to in your previous Comment. I assume the plot3 calls draw the contour levels on the axes, or with respect to mesh, draw planes through them.)
