是否可以在不改变颜色条大小的情况下放大 3D 补丁？我的原图是这样的：

在此处输入图像描述

我只想放大图中中间的块，保持颜色条不变。我以前用过zoom(1.9)，很好，但是因为我需要使用for循环来读取顺序文件来绘制不同的图形并制作视频，所以图形变得越来越大，所以我似乎需要另一种方法来放大情节.

更新：我的代码

set(gcf,'Renderer','zbuffer'); %eliminate unnecessary background and prevent stationary video - Important!
vid = VideoWriter('afation.avi'); %Create a avi file 
vid.Quality = 100;
vid.FrameRate = 15;
open(vid); %Open the avi file so that films can be put into it later on

for ii=FirstFile:FileInterval:LastFile  

fid = fopen(filename,'r');
datacell = textscan(fid, '%f%f%f%f%f%f%f%f'); %There are 8 columns to be read so there are 8 %f
fclose(fid);

all_data = cell2mat(datacell); %converted into a matrix containing all the dis. density info. for every simulation cell

M=zeros(NumBoxX,NumBoxY,NumBoxZ); %create a matrix of 50x50x5,representing array of simulation cells
% % the following loops assign the dislocation density from all_data to M
for i=1:NumBoxX            
    for j=1:NumBoxY        
        for k=1:NumBoxZ     
            num=k+NumBoxZ*(j-1)+NumBoxZ*NumBoxY*(i-1);
            M(i,j,k)=all_data(num,ValCol); %the ValCol column of all_data is dislocation density 
        end
    end
end

indPatch=1:numel(M);
[F,V,C]=ind2patch(indPatch,M,'v'); %Call the function ind2patch in order to plot 3D cube with color

title('AA in different cells','fontsize',20);%set title \sigma_{xx}
xlabel('y','fontsize',20);ylabel('x','fontsize',20); zlabel('z','fontsize',20); hold on;
set(get(gca,'xlabel'),'Position',[5 -50 30]); %set position of axis label
set(get(gca,'ylabel'),'Position',[5 50 -15]);
set(get(gca,'zlabel'),'Position',[64 190 -60]);
patch('Faces',F,'Vertices',V,'FaceColor','flat','CData',C,'EdgeColor','k','FaceAlpha',0.5);
axis equal; view(3); axis tight; axis vis3d; grid off;
colormap(cMap);
caxis([MinDis MaxDis]); %set the range of the colorbar   %caxis([min(M(:)) max(M(:))]); %range of the colorbar according to one file only
cb = colorbar;     % create the colorbar
set(get(cb,'title'),'string','aaty(m^{-2})','fontsize',20); 

lbpos = get(cb,'title'); % get the handle of the colorbar title
set(lbpos,'units','normalized','position',[0,1.04]);
MyAxes=gca;
set(MyAxes,'Units','Normalized','position',[0.05,0.1,0.8,0.8]);

zoom(1.9);
writeVideo(vid, getframe(gcf)); %get the picture and put in the avi file with the handle "vid"

end

close(vid); %close the avi file after putting all the films into it
% winopen('ggggon.avi'); %play the movie

我将缩放放在for循环中，因为我需要将图片一张一张放大并放入我的avi文件中以制作电影。
