Matlab的如何在z轴改变contourf地块的位置 [英] Matlab how to change contourf plot's location on z axis

问题描述

我有一个三维表面，我的身影冲浪（X，Y，Z）

I have a 3d surface in my figure surf(x,y,z)

我也有一个 contourf 表面（这基本上是一个二维平面）。

I also have a contourf surface (which is basically a 2D plane).

我绘制它们在同一个数字，但对 contourf 剧情自动为 Z = 0 的水平。我想了 contourf 剧情移至 Z = -10 （或Z轴的任意值），但我T做到这一点。

I plot them in the same figure but the contourf plot is automatically at z=0 level. I want to move the contourf plot to z=-10 (or any value on z-axis) but I can't do it.

我相信这是容易的，但我无法找到在MATLAB帮助/谷歌的答案。 任何想法？

I am sure it is easy but I can't find the answer in MATLAB help/Google. Any ideas?

推荐答案

请看下面的例子：

%# plot surface and contour
Z = peaks;
surf(Z), hold on
[~,h] = contourf(Z);       %# get handle to contourgroup object

%# change the ZData property of the inner patches
hh = get(h,'Children');    %# get handles to patch objects
for i=1:numel(hh)
    zdata = ones(size( get(hh(i),'XData') ));
    set(hh(i), 'ZData',-10*zdata)
end
