我真的希望这不是我错过的一些愚蠢的小东西，但我已经尝试了几个小时来解决这个问题，但没有取得任何进展。基本上，我创建了一个带有 3 个子图的图形。为了简洁起见，我制作了一个设置绘图的函数，然后我创建了另一个函数，它使用实时数据不断更新绘图。

问题是，在实时更新功能中，第三个子图工作得很好，但现在我希望我的第二个子图也能实时更新，我还没有完成。出于某种原因，每当我输入代码以访问第二个情节时，它都会不断更新第三个情节并直接覆盖它！与此同时，第二个情节保持在它的初始状态......

这是代码......我已经查看了十亿次，所以我现在不知所措，我不知道还能做什么......就像我说的那样真的希望它不是什么愚蠢的大声笑......谢谢一堆=）。

编辑：出错的部分从它说“%refresh plot

这是我设置情节的功能

function [Fig] = EndoSliceViewer_createFigure(Figindex)
%This function creates and returns a Figure object to visualizes DICOM data
%in the plane orthogonal to the endoscopic view, the RGB view of the camera
%and the orientation of the navigation

%set resolution for Endo Slice Plot
Fig.resolEndoSlice=300; 
Fig.resolEndoRGB=[720 1280]; 
Fig.resolEndoNavi=[500 500 500]; 

%init figure on screen
Fig.fig=figure(Figindex); gcf;
set(Fig.fig,'Position',[50 500 1500 500],'Name','Endo Slice Viewer');
%set(Fig.fig,'KeyPressFcn','global kpressed; global Fig; kpressed = get(Fig.fig,''CurrentChar'');');

Fig.sub1=subplot(1,3,1);
Fig.sub1im=image(uint8(zeros(Fig.resolEndoRGB(1), Fig.resolEndoRGB(2),3)));
title('Endo Camera View');
daspect([1 1 1]);

Fig.sub2=subplot(1,3,2);
Fig.BoxX=[0;1;1;0;0;0;1;1;0;0;1;1;1;1;1;0;0]*Fig.resolEndoNavi(1);
Fig.BoxY=[0;0;1;1;0;0;0;1;1;1;1;1;0;0;0;0;1]*Fig.resolEndoNavi(2);
Fig.BoxZ=[0;0;0;0;0;1;1;1;1;0;0;1;1;0;1;1;1]*Fig.resolEndoNavi(3);
Fig.sub2im=plot3(Fig.BoxX,Fig.BoxY,Fig.BoxZ);
title('Navigation View');
xlim([-0.2*Fig.resolEndoNavi(1),  1.2*Fig.resolEndoNavi(1)]);
ylim([-0.2*Fig.resolEndoNavi(2),  1.2*Fig.resolEndoNavi(2)]);
zlim([-0.2*Fig.resolEndoNavi(3),  1.2*Fig.resolEndoNavi(3)]);
xlabel('X [vox]');
ylabel('Y [vox]');
zlabel('Z [vox]');
daspect([1 1 1]);

Fig.sub3=subplot(1,3,3);
Fig.sub3im=imagesc(zeros(Fig.resolEndoSlice, Fig.resolEndoSlice));

%potentially: add subplot for navigation position display later

在绘制任何内容之前，您需要将第二个子图设置为当前轴。您可以axes(Fig.sub2)在绘图命令之前使用。
