Hi, everybody,I have draw a scatter3 picture and I want to add some counter lines in this piture. Any one can help me ? after using this,
as you can see there are discrete points， but a lot of ponit have same value(z), so I want to add some counter lines to it like the next picture
what's more, my data(x,y,z) is discrete, all of them are

As KSSV said, you just need to call 'hold on;' to plot both graphs on the same figure. I don't know exactly what your data looks like, but here is some example code that shows how to get a scatter plot and a contour map on the same figure.
x = -2:0.25:2;
y = -2:0.25:2;
z = x.*exp(-x.^2-y.^2);
scatter3(x, y, z);
[X,Y] = meshgrid(x);
Z = X.*exp(-X.^2-Y.^2);
I hope you find this example helpful. Good luck on your project!
