Matlab 在图形中移动曲线

如你所见，在第一张图片中，我有两个子图，两个相同，具有相同的曲线位置。但我需要更改其中一个子地块的曲线位置/或视角（现在不管是左视图还是右视图）。唯一有效的命令是CameraViewAngle，但这两个命令都会更改，我不知道为什么，我需要能够分别为每个命令更改。 如图2中所示，两个视图的视角都发生了变化。我宁愿只改变曲线位置

我使用的代码是：

function [pointsQRS, pointsP, pointsT] = VCG (pointsQRS,pointsP,pointsT)


global ax1 ax2 h

figure('Name','Vektorkardiogram','NumberTitle','off','Color',[0.8 0.8 0.8])

linkaxes([ax1, ax2])

我需要它来改变它，以实现三维立体视图使用谷歌纸板。 提前感谢您的帮助

PS：例如，我想实现如图3所示的目标 但在这三幅图中，3D曲线没有连接，连接的意思是，当我移动其中一条曲线时，另一条曲线将以相同的方式移动

---

我设法解决了部分问题

更改

CameraViewAngle

，会修改曲线的大小，因此我决定保持曲线不变

不要设置角度，而是将

ax2

的

CameraPosition

设置为与

ax1

不同，但与目标保持相同的距离

我没有使用

linkprop

，而是使用并实现了一个回调函数，在修改

ax1

的

CameraPosition

时，设置

ax2

的

CameraPosition

阅读以下参考页：

尝试不调用

linkaxes（[ax1，ax2]）

。这样可以解决问题，但出现了另一个问题，左图要小得多。请参见问题中的编辑，最后一张图片，左侧的figure/3D曲线要小得多。你知道为什么picutre比另一个小吗？你能让你发布的代码在其他机器上执行吗？将一些数据放入

pointsQRS、pointsP、pointsT

中，并参考

mArrow3

函数。您可以在此处下载mArrow3函数：我的代码中唯一可以使用的修改如下：对于我做的数据：pointsQRS=1:3:78；点SP=1:2:92；pointsT=1:1:85；我在GUI中选择的特定数据，因此无法填写我正在使用的确切数据。但是mArrow3函数所做的轴的视角也很明显。我设法得到了一个部分解决方案，请让我知道它是否仍然相关。我可能有一个误解，我不想要一个单独的控件，相同的控件，只需更改曲线的视角。我已经做了你的建议，它是连接的，但再次，左边的3D曲线更小，它在移动时改变了它的大小。PS：我需要保持相同的大小，保持连接，只是改变曲线的位置/视角。今天晚些时候你有时间吗？
