我正在尝试在由虚线连接的3个不同平面中制作带有点的3d图。 数据分为两组：
第1组我正在尝试连接黑色半透明虚线 - 这里我遇到了麻烦。
第2组我试图用黑色半透明虚线连接 - 效果很好。
在第1组中，似乎matlab在彼此的顶部绘制了两条线，一条半透明的法线，顶部有一条虚线不透明线。两条线的代码相同，只有数据和颜色不同。
这是我的整个代码：
data = xlsread('rdata.xlsx','PCOA','A2:E43');
weight = xlsread('rdata.xlsx','PCOA','A45:C45');
data(:,1)= -data(:,1);
depl0 = data(1:7,[1,2]);
deol4 = data(8:14,[1,2]);
depl9 = data(15:21,[1,2]);
undepl0 = data(22:28,[1,2]);
undepl4 = data(29:35,[1,2]);
undepl9 = data(36:42,[1,2]);
depl0 = [ones(7,1),depl0];
deol4 = [2*ones(7,1),deol4];
depl9 = [3*ones(7,1),depl9];
undepl0 = [ones(7,1),undepl0];
undepl4 = [2*ones(7,1),undepl4];
undepl9 = [3*ones(7,1),undepl9];

我希望DTR +组的线看起来与DTR组相似。

我发现了问题。
显然，出现不同的线条是由特定视角产生的伪影。当我在视图窗口中手动旋转图形时，线条显示为所需的虚线......
