具有连接点的3D散点图Matlab

Question

我想在Matlab中的3d散点图中连接具有相同Z值的点。

num=1e2;
x=rand(num,1);
y=rand(num,1);
z=zeros(num,1);
z(randsample(num,.25*num),:)=1;
scatter3(x,y,z);hold on;scatter3(x1,y1,z1);hold on;
%connect dots with same Z value, so there should be horizontal line between points in the same Z plane

Answer 1

当您说“连接点”时，我不确定您的想法，但这是一个方向：

figure, hold on
for u = unique(z(:))'
    plot3(x(z == u), y(z == u), z(z == u))
end
view(-37.5, 30)

另外，也许您可​​以修改数据并改用contour3命令。
